Well it looks like the rumours were true and the Payday gang have their very own time machine.

The heist is basically the same as the original from PD:TH with a few key differences, mostly just a few different locations for doors.

It's not a bad heist and the map is nice. :)

The pathing for the civis is horrible. But once they're there, they tend to stay there. Just try to get them right behind the wall so cops don't start saving them because the same cop will just chain save them all.
You should have enough time to tie/move civis before too many cops turn up anyway.

This one is very easy if you know the map and can stealth it well. Hell chances are you'll probably get it while practicing stealth, there's more than enough time to do it.
Any difficulty works, but lower means less guards and bags to deal with.

"In the First World Bank job, complete the heist from start on the OVERKILL difficulty or above with a full player lobby using all 4 characters from the PAYDAY: The Heist crew, Reinfeld Shotguns and Bernetti 9 Pistols."

Is the full description for this one, Steam tends to cut it off.

Do not even try to pub this one, it will not go well.
I've seen this done on DW but since the Reinfeld is nerfed into the ground, my advice is do it on Overkill.

The team you need is: Dallas, Wolf, Chains and Hoxton (not Houston).
Any build will do, but chances are your concelment will be too high to run a Low Blow/Sneaky Bastard build.

The achivement kinda doesn't explain this one well.

First up you have to throw the required number of bags into the vent, this triggers the prompt for C4 to be put on the wall, then you have to move all the rest of the loot without the vent. It's like the ♥♥♥♥ It, We're Walking achivement but a little bit easier, since there aren't too many cops in the way.

Just do the heist on DW, no biggy.

In Stealth you can clear out the vault area easily, so you can get all the bags to the vent in peace.
Chances are solo you won't have enough ties since you have to tie the manager, the 3 people in the vault area and the ton of civis in the building next to the bank.

Loud is good practice for when you want to do Overdrill :)

Here we are, the big one.
First up, learn the puzzle beforehand. Either by doing it in PD:TH or watching vids on it or reading a guide (like this one :3 ).

I actually drew the tiles and the puzzle so it wouldn't have to look it up mid game.
Basically I drew both floor plans and the correct tiles. The tiles are outlined, but it's a very very fine outline so be very careful when you go to interact with them. Best thing to do is send 1 person to do the puzzle so no one else gets in the way or hits the wrong tile. They should be defending anyway.

Next is builds. We went: 1 Techforcer, 1 Ghostforcer (muscle deck with ECM feedback aced), 1 Masterghost and 1 Masterfugi (rocking 3 concelment).
Depolyables were 4x maxed doctor bags, 2x maxed ammo bags, 2x maxed ECMs, with feedback. In hindsight we should of taken more ammo, and told the Masterfugi to not bring his pistol crossbow, but what's done is done.

Best thing to do is stick together. If you get separated chances are you'll get blocked by a Skully or just a hoard of weak cops. Even if the drill breaks, it's best to get the hack done first then focus on the drill.

Aside from that you just have to hold out for the 2000 seconds. Cops spawn from the elevators in the pillar room, the vents and will wander in from outside. If you can hold the pillar room, it's not too hard to get the loot moved.

Video:
Skip to 43:30 for the puzzle.

There are 70 bags of gold in the secret vault and they can be tossed into the vent.

When you go to leave remember:
- A SWAT turret will pull up in the lobby.
- There are 3 green dozers in the ajoining offices.
- Shields are in the corridors.
- Another Dozer that comes out of a random door in the corridors
- Cops don't spawn near the escape/vent exit but will make their way down the stairs/corridors from either the bank or offices.

This one is very simple.
When you escape into the other building in a random spot, before the stairs down, there is a titan safe. Drill it and the ticket will be inside.

Still, aside from Overdrill, there's nothing too hard here. I found Original Heisters fun and the map is nice to play on. There are a few issues, mostly that civi pathing issue but it's a fairly solid heist.

Multiple achives can be done in the one run but you need a good few to get them all. I think I have a -15% xp penalty currently because I've played this heist so much.
