I would like to start with modifications for Portal 2 from Steam, since they are the most accessible to the average Steam user. Such modifications can be downloaded from the Steam store after purchasing Portal 2, they are added to the library, so you can easily find them after downloading)

▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
I'll start with my favorite modification called Aperture Tag, don't let the long name scare you, this modification gives you the opportunity to use a paint gun that can spray blue and orange gel wherever you want, this mod will give you a really new gameplay because the mechanics of the game is completely changed, but it's still the Portal, here is the download link https://gtm.you1.cn/storesteam/app/280740/Aperture_Tag_The_Paint_Gun_Testing_Initiative/
the only negative is the paid mod
(requires Portal 2)
▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
There is also a great mod, it's called Portal Stories: Mel, this is the story of one character, as you understand by the name, this mod will suit you if you like to solve complex puzzles and you didn't have enough locations in the style of the old Aperture cases, what can I say, if we were given the first prototype of the gun portal, in general, I recommend it, link https://gtm.you1.cn/storesteam/app/317400/Portal_Stories_Mel/

There is another mod on steam that might be of interest to you - Thinking with Time Machine. One of my friends even had a hand in its creation (he wrote the plot), in this modification all the textures were redesigned, new mechanics were added and a very interesting storyline, in general, you will like it, download in steam here https://gtm.you1.cn/storesteam/app/286080/Thinking_with_Time_Machine/

A small digression, the next mod is not for Portal 2, but for the first part, respectively, for Portal, but the mod itself does not get worse from this fact)
▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
A very interesting mod for the first portal, but now all the puzzles will be related to plasma balls, the puzzles themselves are quite complex and will make you think, so you have a lot of content to pass, and also the motivation to return to 2007 and nostalgic, here is a link to this creation https://gtm.you1.cn/storesteam/app/317790/Rexaura/

Another mod, it has new mechanics, and it is very interesting, of course, there has been something similar in the workshop for a long time, but in this mod this mechanic is elevated to absolute - the third portal for moving in time! The developers have worked out various rules for time travel and it makes you think a lot when going through the test chambers, I think the creators of the mod turned out to be interesting puzzles, but it looks kind of hacky, but most likely all the forces were thrown into working out new mechanics, I think this justifies all the shortcomings https://gtm.you1.cn/storesteam/app/1255980/Portal_Reloaded/

I don’t know what to say about it, because the video card is a little short of me. It has mixed reviews, but I can not play it :P I advise you to play it in order to have your own opinion.
The game changed the textures, changed the lighting, added a reflection. This is not at all like Portal Remake Mod, not in terms of the fact that the remake mod is ♥♥♥♥, but in terms of the fact that they are completely different.

The same as the Portal with the newfangled PTX, but the Prelude, which will be discussed below. I would say that this is a good option to get acquainted with one of the legendary or not so legendary mods, but... This statement is debatable, as is the reputation of the mod, because you have a video camera with PTX? I don’t have this, but for those who do, lags are not uncommon.

Finally! Portal in VR! Well, it’s a beautiful graphic according to the screenshots, I didn’t manage to play it myself, since I don’t have a VR helmet, but I think it’s an interesting gaming experience.

A controversial modification to be honest, its main feature is the ability to interact with a new gadget, a motion capture, but this is also the main disadvantage, the modification itself is free, but exclusive to this device, you won’t be able to play without that crap, which means you'll have to spend money. The mechanics are new, of course interesting and all that, but there’s nothing else in the mod, simple cards without a special plot, it’s better to buy Aperture Tag, it will be more interesting and cheaper.
https://gtm.you1.cn/storesteam/app/247120/Portal_2_Sixense_Perceptual_Pack/
I recently read a post on VK, where they told a lot of interesting information about this mod and how you can play it, here >>ссылка<<[vk.com]

Another small digression, these modifications have not yet been released on Steam.

▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
This is a very interesting modification, judging by the screenshots, video and description. In this mod, one of the personality modules awakens you to finally destroy GlaDOS, well, apparently they didn’t succeed ... The developer promises that not only interesting maps will be in the mod, but also new mechanics, he wants return some cut content: riddles with pneumatic pipes, purple gel, which is very sticky and allows you to walk on the walls and ceiling, as well as a not very clear thing called a schloedenger cube, don't ask what it is, I didn't quite understand it myself) Well, I I really look forward to the release of this mod, because the author continues his work on the mod and the release was scheduled for 2022, well, let's hope
that there will be no transfers)
Thank you, the author of the modification, for personally providing me with information for the guide! Tewan thanks for the info!

According to the plot, our main character signed up for the Aperture testing program. Now he has to undergo tests in the old Aperture complex. All this takes place in 1998, a little after the death of Cave Johnson. The whole story will stretch over 5 chapters. They promise 4 new characters, many new mechanics and new locations! I really liked the concepts, screens and videos, the developers did their best with new models. I think it will be a cool mod, it's a pity that it will be released only in 2024.

Portal 2: Community Edition

A modification that promises to return the cut content from Portal 2, they want to add multi-colored lasers, cubes that can teleport a laser, reflective and sticky gels and much more, I think that there will also be a lot of puzzles so that we can try out all the new mechanics and wonder why the developers cut it out?

Maybe you've heard, or maybe you haven't heard, about such a promotion as GreenLight. Once upon a time, Valve paid attention to projects that wanted to go to Steam and were supported by the community, such projects entered GreenLight, and with the support of Valve came out shared on Steam. Also in GreenLight various modifications for our beloved Portal took part, both for parts 1 and 2, but out of 9 only 4 were released and another mod is being prepared for release, which I have already talked about in the previous paragraph, now I will tell you about those that were never released on Steam, and believe me, we missed a lot...

According to the plot of the mod, we wake up in the stasis chamber of the Expanded Relaxation Complex 1976 of the year. The complex is barely breathing and crumbling, and you need to get out of this place. I liked what I was able to download from Moddb, very atmospheric, the puzzles are interesting, especially because they are not presented in the form of ordinary test chambers, I think you should look at what the author has done so far on Moddb and support it, here is the link to the page Moddb Desolation

The author promises a complete transfer of the game to new rails, so to speak, optimization, bug fixes, etc. The textures used are new from Portal 2, but this is a custom remake, so there will be new levels, new explosive elements And even damn it a crowbar with a gravity gun, the author wanted to put it in this mod, it sounds promising, well, let's hope that something good will come out) This mod is on Moddb, see what the author got from the link Moddb Remake Mod

This mod has a very cool design, everything is so neon, very mesmerizing, I just wanted to play it because of the screenshots of this mod) on the old complex Apertur, I didn’t learn more about the plot, but the author promises that the history of the mod will consist of two parts, well, let’s hope that at least the first part he will do)

Abyss (mod name) very interesting mod, such a gloomy environment, it sometimes scares, although the author did not even think about it. There are several endings in the mod and they depend on the path you choose, puzzles contain action elements, where you need to parkour, where you need to react quickly, etc. And according to the plot, here we are again a survivor after the 7 hour war and we found an abandoned complex Apertur, or rather, you just fell into the depths of the complex and you apparently need to get out. The atmospheric mod is also very interesting, you should definitely look at the mod page on Moddb, here is the link Moddb Abyss

This mod is called Isolation for a reason, because this mod makes Portal a stealth horror with an eye to Alien Isolation. We play as an astronaut who flew the last rocket to the moon in 1950, but of course something went wrong... That's all I know so far.

It doesn't matter if these mods got into the workshop or vice versa, the main thing is that you can play them, both in a full mod and as a set of cards, without bothering with installing the mods themselves, which I did :P

This mod recreates the mechanics of the canceled Valve game "F-STOP", which was supposed to be a prequel to the first Portal. The style is just awesome, you don’t often see such retrofuturism, plus a new mechanic that was supposed to be the main feature of the canceled game, this is a camera that can transfer objects to photographs, and then back, and also increase and decrease them! And the author of the mod is Russian - laVashik, who has been doing this with the Portal throughout its modeling career and you definitely need to see what he has done now! I think such an ambitious and wonderful project should be supported without fail. Here is >>link<< to the map pack, the author calls it a demo for a full mod. And here is the link to the page Moddb F-stop | Project Capture, where you should most likely wait for a full-fledged mod.

There are also two endings, only the ending with the boss fight disappointed me, the fight was boring, and for some reason the AI ​​of the turrets was turned off ... But despite this, I went through the mod more than once. The environment in the mod is very well designed, the bts elements are very cool built, and how many easter eggs are here, too much for a regular mod :P I was very interested and I hope you enjoy this mod, here is a link to the page Moddb Aperture : Déjà vu[https//www.+moddb.com]

BEE2 or Better Extended Editor is a mod that many times expands the capabilities of the usual built-in in Portal 2 map editor called PeTI. I think those who always wanted to do something unusual for the portal lacked the functionality of an internal editor, and studying Hammer is more expensive for themselves, although it is still much more functional, but the functions of BEE2 will be enough for you with your head.

Note: this is not exactly a mod in the usual sense, it is a program that will modify the original Portal 2, or to be more precise, it modifies PeTI, because of the many limitations of this editor, the mod has to work on crutches, but it works.

For those who do not know what Moddb is - stands for mod data base, translated into Russian it is the Mods Information Base, this is the site where various modifications for different games, for example for Half life, Portal, and for their next parts, etc.
Most of the mods have to be downloaded from Moddb, which is not very easy and a bit of a chore, but the huge scope of mods compensates for this lack, although I still don’t mess with the files like it.

How could I not talk about the mod - port of the game Portal: Still Alive, which was made exclusively for consoles, and many levels were taken from the map pack for Portal - Flash Portal. A very strange mod, but interesting, why not go through something official on the Portal, since this is a port of a real-life and official game for consoles . Also this mod already has the Flash Portal mappack installed, so I recommend taking a look at that as well. Here is the link Moddb Still Alive (requires Portal)

This mod consists of 2 episodes. It is quite strange, the plot is rather sad and apparently takes place in an alternative universe Portal, also new test elements have been added to the mod and puzzles with them are interesting. And oddities to this fashion give incomprehensible events and objects sometimes flashing on the screen. And in this mod there is a very difficult alternative ending to get, I think you are already interested) Here is a link to Moddb Factum Solus

as I understand it was a game made in Unity for phones. It was crooked and slanting, but still a game similar to Portal for mobile phones. and this mod can be called a port to the usual Portal. Modification looks quite stylish with a bunch of new test elements. And the last levels are very difficult, especially because of the final boss, I did not understand what to do(if you need help, write in the comments).

I actually have very mixed feelings about this mod even though it doesn't have a sane plot and it looks awful. But the mod is a little interesting to play, and there are people in this mod, and there is even a location that can be called a demake of the old laboratories from the second part.

You may not be surprised that there are few mods in this category. It's just that most Portal 2 mods are in other categories.

▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
The mod is not quite a normal mod, in each chapter of this mod you will collect personality modules to advance further, with each chapter []is very different[/i] in design from the other, and all the tests are kind of like simulation, if I understood everything correctly, an interesting mod, but it could be finished, but apparently the mod is abandoned and there is no one to finish the mod...

Remember, literally in the last category I told you about the Portal: Unity mod? It's good that you remember, you're not sclerosis like me... Well, this mod is a reboot of Portal: Unity, like a remaster, if someone doesn't understand. I think that this mod is made much better than the original, in the original everything was so clumsy, but here it's normal. If Portal: Unity could be called controversial, then I wouldn’t argue here, it’s a great mod, the only negative is that it’s not finished, not all of the original mod was transferred, well, in some places it was transferred with changes, but as for me it is not so important.

This mod is quite unusual. The mod decided to create puzzles closer to those in Half-Life, adding the ability to run, as well as adding fields that slow down time. Because of this, the mod turned out to be quite complicated, because you don’t need to think much here, the main thing is to jump correctly, have time to run, etc. But on the other hand, there are normal such plot pieces and cutscenes in fashion, I will not spoil it. And there are even collectibles, so look for secrets :P And the visual style is interesting, it looks beautiful and unusual. But as I understand the mod is not completed and I did not see the normal end ...

Quite difficult mod, but interesting! The puzzles are hard, but not tricky, you don't have to build a three-story puzzle solution to complete it on the fifth try, they're just hard puzzles that you have to figure out. Although "Bonus Cards" did not succumb to me, what can I say, I still need to try to open them. But I think wasted time well, stretched my brain well and found out where the field came from, which gives a signal when passing through it in BEE mode :3

This is a very unusual mod for Portal 2, it has a very simple and strange design, but this is its feature. Also, the puzzles are not difficult, no new mechanics, but still unusual.

I really liked the mod, though it's not a puzzle. The author of the mod collected all the abstract cards of his friend and explained the meaning of these cards, it was very interesting for me to follow the author’s reasoning, albeit in a hurry to read subtitles, by the way there is a patch for Russian translation, plus the author got hold of cards that his friend never put it in the workshop, exclusive!, here is a link to the page Moddb Draw me a World

another abstract mod, the whole world is white and you can paint it with black paint to understand the outlines of the environment, I think the author wanted to show how some people with mental disorders see the world, since fashion comes out of the fools(psychiatric hospital).

Although this is a demo, I still put this mod here, because it is abstract. Yes, the mod is drug addiction, but it's cool, funny and sometimes boring, because there are conversations of the off-screen announcer for half an hour, there are also no subtitles, but there is a reference to MINECRAFT and something else, and there is even an initial screensaver with a man with valve was replaced.

And now let's move on from the advanced graphon to optimization. This mod makes most of the textures monotonous, and generally smoothes everything that is possible, simplifying the models and textures, you can see in the screenshot.

Didn't it seem strange to you that the style of test chambers in Portal is so different from Portal 2? To be honest, no, but if this bothers you, then here is a mod that will replace a lot of textures and models in Portal with analogues from Portal 2. In fact, that's it, it was actually unusual to run in the good old test chambers, but with new surroundings, the same feeling I experienced when going through Gamma Energy. By the way, you can additionally recolor the portals and the portal gun, just like the Atlas. If you are interested in the mod, here is a link to the page Moddb Portal 2 SkinPack for Portal 1 v1 .5

The mod looks very stylish, the author of the mod did a good job on the visual part of the mod. There's even a new mechanic here, well, it's not that interesting. Well, there is no plot either. But I think it doesn’t matter, it was enough for me just to play in this unusual environment, because literally everything was redrawn and redone in the visual part.

The mod is unusual in its concept, mixing Portal and Half-Life, that's what attracted me. Although in fact this is Half-Life, but in the style of the Portal, but still interesting, by the way, the mod reminded me of Portal Relocation, only in Relocation, on the contrary, they make a portal in the style of half life.

It seems to be a map pack, but it's a full-fledged mod, there's even a plot, well, the usual one for Portal, you pass tests, then they want to kill you, you are trying to get out, but as I understand it die. Sorry. Not bad for the first Portal, but I didn't like some points, I would give medium rating, pulls all stylish redrawn textures, and there is also a new test element, it is similar to a bridge dense light, only pink or purple, it's up to you) Here is a link to the page on Moddb Hazmat's Portal

In fact, these are just a pack of cards, not even in the wrap of fashion, that is, you will have to throw the cards into the portal 2 into the folder, and then launch these cards through the console, I consider it a little lazy from the developer. I didn’t like the cards themselves, beautiful, but confusing, you cannot understand what you need to do, and then they also become dreary, etc. There is a secret that you can open by finding 10 hidden levers, it was interesting to look for them, but not for long.

I expected something more, but I got a one-room puzzle, and a primitive puzzle over time. Of course, I did not understand anything from the subtitles. I think the author planned to do something like "escape from the room", where we would need to move in time, looking for new ways to solve the initial puzzle. But it didn’t work out, and it even turned out quite crookedly. By the way, at Moddb CHRONOPORT you won't be able to find where to download the mod, well, at least I didn't find it. One friend helped me download, and I will say this, you don’t even have to take a steam bath and look for where to download it, it’s not worth it.

Very, very bad mod, but "full". Most of the maps have a strange and illogical level design, the textures are crooked in some places, the skybox has no texture, and the voice acting... if I played with headphones at high volume, then I'm sure that from this squeak and squeal, which supposedly make the voice robotic, my ears bled. For that, this mod has a full-fledged and rather long company, but it was rather a burden for me to go through this mod for so long. Well, I can also praise for the introduction of ball mines and manheks into the puzzles, but again, the author of the puzzles did not particularly disclose them as test elements.

Such mods have not yet been released and are being actively developed by the authors, since I did not manage to play these mods for an obvious reason, I went to different Discord channels of the author of the modifications and asked them to knock out the right bit of information. It seems to me that there are some people who are sitting on all active servers of mod developers and I think that this Russian is walking around here and beating mod developers)

A wonderful mod from our countrymen, with a very original idea, to move the scene from Aperture to Black Mesa, a direct competitor. And also moving to Xen will be one of the mechanics of the mod, it’s also possible to use my ideas there :P Although I can’t say a lot of things yet, because although the mod is being actively developed, it started relatively recently and a lot of things are not ready, but I still hope that my friend and his team will succeed!

Another mod in an alternate universe. This time, Aperture and Black Meza did not compete, but rather collaborated, Mesa
provided Aperture with a large black hole. But this universe was not bypassed by the tragedy with Glados and its neurotoxin, because of this there is no one to monitor the big black hole and soon it will collapse. And it seems like our heroine or hero should prevent this from happening. The mod is interesting, reminded me of Abyss with its gloomy atmosphere. In general, it seems to me that this mod and the Portal: Relocation mod are in the same universe, and here and there the collaboration of Black Mesa and Aperture Science, it seems there should be mutual references.

The mod is a connecting element between the first and second parts of the Portal, we will find out what happened after the destruction of Glados in the first part and what unknown force made the complex survive and change beyond recognition. As you can understand, the style of this mod will combine the style of the first and second Portal, which I really like. Here is the Moddb Portal: Catalyst

Fool Whitley, transporting Chell, knocks our room down, and she falls down. We wake up outside the room and see the yellow inscription Test Shaft 06. I was able to find out that there will be new mechanics in fashion with fans that will either blow you away or attract you, somewhere I saw it ...

A very interesting mod in terms of visuals, this green fog looks mysterious, the mod itself continues the story of Portal 2, where a virus, either a computer one captured the complex, or a biological virus filled the airspace of the laboratory, it’s not exactly clear. The author says that he wants to release a demo, where you can learn more about the plot. The current development progress of the mod is 30%. Demo version progress: 67%.

I already meet somewhere a mod about adventures on the moon, but it didn’t work for me, I hope this mod will be very good and someday it will be released. The action of the mod will take place on the moon, the developers said that they concentrate on the puzzles themselves and that they should be interesting and unusual, will be added ]new elements and diversity of puzzles with gravity, I hope so, since in the workshop the variety of such maps leaves much to be desired, I hope there will be at least some plot, and not about him forget.

And now let's remember the first Portal, yes, at least one mod is still being actively sawed for it, here it is. But you didn’t think that this was where his uniqueness ended, did you? No, of course, in this mod they want to implement something like a semi-open world, in which you, playing as a Chell clone, at the request of one scientist, escape from the usual test route to the backstage, even get the opportunity to hack devices... In general, DeusEx with an amendment on the possibilities of the Portal. Of the new mechanics, you can notice the “degradation” device and the portalgan improvement device, that is, during the gameplay you will have to leave the two portals you are used to and play with one, and then vice versa, such mechanics were implemented in Faktum Soul, but here they just got tired of the animation which is worthy of praise. There are also buttons and cubes that are labeled in a special way, and only a cube with the same label as the button will be able to press it. I think this is enough to get interested in the project, so here is a link to the mod page at Moddb Portal: Ambition

These mods, unlike the previous ones, are not actively developed, the development of some is frozen, and some are completely abandoned and may never come out at all, but I will hope that the developers will succeed!

The mod is very beautiful and unusual, judging by the trailers. But so far little is known, it is not known what will be in it when it comes out, etc. On the page, the plot line is written that there was an Aperture division that explored something under some island and invented a time machine that influenced the whole world. The plot is interesting, especially after watching the trailer, I hope the mod will not be abandoned and it will be released.

A very beautiful mod, the graphics in it are what you need, and a very elaborate mapping. I really want to play this mod already, I hope it will be completed someday. And, what is there according to the plot, so so, we play for one of the people who were found at the end of the Second Portal cooperative, but our main character got out of prison earlier due to a malfunction of the capsule in which he was stored... That's it. Not a lot, but what can you do. By the way, in this mod there should be a new model of the portal gun, but we woke up in the old laboratories, like Mel, maybe new mechanics will be associated with this? Possibly, but no information yet. If you are interested, here is a link to Moddb Repercussions

I would say that this mod is the most alive among all the mods in this category, but still there is one point. But perhaps it is necessary to tell first about the fashion itself. This is another unreleased remake Portal, is it some kind of curse? Why has not a single full-fledged remake been released ... Well, I have high hopes for this mod, according to Moddb, the mod is almost ready, but due to the fact that one person is currently working on it, it is not known when everything will be ready. But I will hope and wait, and Moddb Alive & Kicking

This mod is a continuation of the co-op story in Portal 2. In this mod, we will be playing as one of the awakened people from the stasis chambers that Atlas and P-Body found. Because GlaDOS is lazy, she's spread the surveillance of people taking tests into different personality modules, and we're one of the people who will try to escape. The mod is interesting to me, it's like the Thinking With Time Machine mod, because they continue the story of the original Portal 2. Here is a link to the mod's page at Moddb Backstock

This is a redux version of the game Flash Portal for Portal 2, the game is based on the game itself, not the mappack, which was created by the developers of the game for Portal, but it will still be something else, because the author has redesigned or removed some puzzles, as well as the whole mod is made in a mixed style Portal 2 and Portal (Portal 2 prevails), all new test elements also changed their appearance, stylized for Portal 2. Nothing is known about the final boss, the author wanted to make it, if possible, and also change it, since the fight with him was a bit strange. Here is a link to the Moddb Portal 2:TFV

The mod is at a very early stage of development, but I was attracted by the idea of ​​​​creating puzzles with 4 portals, it will be just a brain blast! There is nothing more to say, it is not even clear what the mod itself will look like, there is only a model of the portal gun, and the model is not one of the most detailed... In general, the idea is good, but there is no implementation yet, in general, and the developmen Moddb Portal: Subservient

The mod looks chic, the plot in general: Kick the Earth, Aperture moved to Encelad and conducts tests there, design style looks very cool, you really understand that the future is already under your feet, I'm just sure that if the author finds time to finish this mod, it will be one of the best mods, you me ask: Why? and I will answer, the cards from this author in the workshop are gorgeous, complex and interesting! Here is a link to author's profile, I advise you to go through his maps, if the maps are awesome, then a full-fledged mod will come out even cooler)

And now we're going back in time! This is a very unusual mod, because it tells about the dying thoughts of Cave Johnson, and yes, in this mod our Cave, and the mod will not deprive us puzzles, because in this mod Cave Johnson himself will pass the tests) Also in this mod we will see GlaDOS before it turns into GlaDOS, that is we will see Cave's main assistant - Caroline. By the way, it turns out that this mod can be called horror, I was surprised when I heard it, but I doubt that there will be stupid screamers and stuff like that) Here is a link to the mod page on Moddb Valhalla

Hm, 77, what does that mean? I don't know, but I know that in this mod we play as an unknown protagonist, who wanders around the complex under the control of an unknown voice, it sounds mysterious :P The developers say that they have created a new design style, although I didn’t really notice this from the screenshots, but I liked the elaboration of locations, but we will be able to visit both the new and the old Aperture comple Moddb Aperture 77

I certainly know that this is not a mod for Portal 2, but this is a puzzle, on Source! (It says on the Moddb page that this is a mod for Half-Life 2) First of all, I was struck by an unusual visual range, it is not ordinary and because of this cool, retro-futurism is gorgeous. And what about the gameplay? We are given a new multifunctional device - E.C.H.O, with which you can do a lot of all sorts of things: jump high and far, like using a gauss gun, activate, for example, dispensers of cubes, and interact in a certain way with the cubes present. Too bad this game never came out. Here is a link to the mod's page Moddb PUNT
▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
It seems that this mod is a remake of PUNT, for some reason the author decided to make a mod for Half-Life, and for Alien Swarm, a strange decision for me, but not for me to decide . The mod has not yet been released, but I hope that someday it will be finished. The environment, compared to PUNT, has become more futuristic, due to the white color scheme. I can’t say for sure about the new mechanics, there is little information about fashion on the surface. If you are interested, you can visit the page Moddb Vectronic

No, first Vectronic was made for Alien Swarm, and then it was remade for the leadwerks engine
About Alien Swarm
There are 5 iterations of the Source engine: Orange Box, Left 4 Dead, Alien Swarm, Portal 2 and CS:GO. Alien Swarm is newer than Orange Box and is open source. The other 3 iterations are not open source, they have Authoring Tools, not the SDK. That's why Alien Swarm was chosen

And already this mod shows what "F-STOP" itself could be. Considering that the project has been in development for a long time, but nothing has been done yet ... Plus, there is a better analogue. Here is a link for you Moddb Filter Factor

It seemed to me a very interesting idea to combine Half-Life and the Portal, although it turned out that this is partially not what the mod was like. It turned out that this is another Half-LIfe mod with a very delusional plot, where there are simply locations made in the Portal style. I'm disappointed, but it's still clear that the author spent time and most likely did it all alone, the mod is ready, that is, completed, not like some mods that are thrown into the public domain half-finished. Yes, and our fellow countryman made a mod, I think that it’s still worth looking at it, although most likely you will just be bored, although maybe you can just laugh :P

All these mods are abandoned, perhaps forever, but this is not certain. They seemed interesting to me, so I decided to show them to you.

▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰
The main idea of ​​the mod is that Chell never existed, because of this, as if by a butterfly effect, various unusual events occur, Glados makes a deal with Combines and now we will be tested in City-17, which means that the turrets will komabainskie, in the holes of the test chamber one can see the citadel, etc. I was interested in the mod, if you are too, then here is a link to Moddb Scorched Earth Policy

This mod is like one prolonged joke, like this is a mod where texture is specially used, which means no texture, and some kind of game must be going on here, but the main the villain is generally a dog from the meme of one "El Huevo", it seems, did not go deep. Well, you understand what I mean, it will be an abstract post of irony, flavored with memes... By the way, a mod from the creator of the mod Scorched Earth Policy.

This mod reminds me a lot of Thoughts, only the style is bright, but also beautiful, and well, we had to play as Peabody. They promised new locations, where no human foot had set foot, new characters, history and new test elements, it's a pity that all this was not destined to come true. Here is the link to Moddb Portal: Citrus



And here is another unifying detail of this mod and Thoughts, this is a map in the workshop, you can go through it and check out the style of the mod, at least something from this mod is left, here is the link https://gtm.you1.cn/sharedfiles/filedetails/?id=2181569747
