Warning: Dead PVP Game
This game has no meaningful single player content, and no playable PvP servers. There is no functioning PvP population, it's a dead game, and cannot be played as intended.

The Wall is an over ambitious asset flip looking PvP/survival/crafting/whatever game that can't be played because the developer yanked the servers. The developer kept all the money he took from gamers, no refunds were given.

The game was abandoned a couple of years after launch and hasn't been updated in almost 2 years. It blew past the developers commitment to complete the game without any notification or admission of failure from the developer. The game will never be completed.

The mismatched game assets are fairly mediocre/low quality, it's a wonder why they couldn't be bothered "borrowing" higher quality assets for this. This is a lot like going on a shoplifting spree but only stealing the cut price store brand goods. Regardless, the poor quality assets alone should be enough to deter gamers from bothering with this.

The developers made the fatal, lazy mistake of believing that PvP, other players, would be an acceptable substitute for doing the difficult job of adding single player level design, storytelling, NPCs and other rich aspects of designed game content to the game. As a result of this choice by the developers, the game has little to no actual interactive game content. It's a little considered fact that the vast majority of PvP only, multiplayer only games fail. Developers must learn that other players are not an acceptable substitute for doing the job of game developers and building a game filled with content. PvP only games must have a huge player base for them to "go viral" and succeed. But with no single player experience to add lasting value to a game, the developers instead chose to bet against all odds that their game would "go viral" without any actual reason for players to want to play the game. Predictably, they lost this bet.

Compounding this problem, the developers made the terrible mistake of launching a multiplayer only game in Early Access. This is almost certain to kill the game. Most gamers will evaluate a game only once. If they do so when the game is incomplete, they will check it out, then abandon it (just like the developers did). When (IF) the game eventually does get around to release, there will be no players, because the developers burned the first impressions through their faulty Early Access experience. Players who saw the game and didn't like it because it was incomplete do not come back. Multiplayer games must have a large population if they are to go "viral" and succeed, especially without single player content to fall back on. Releasing a multiplayer only game into early access kills the game population, and thus the game, before the game even launches.

Unethically, the developers have left this on the Steam store in a dead, abandoned and unplayable state (because there's no players and no meaningful single player content). It's the responsibility of the developer to maintain their product, ensure it runs on all modern PCs, or if they determine there's defects and the game doesn't work, or the population dies, they should remove it from sale instead of misleadingly trying to scam gamers into buying knowingly dead/unplayable products.

This is harmful to Steam and to gamers, not just because it's a direct and intentional attempt to scam people, but because it takes a share of the marketing space and visibility away from other games. It's polluting Steam and making it harder for gamers to find genuine games and for genuine indie developers who put months or years into making proper games find an audience.
