It's so good, though I have to warn anyone thinking about getting this game! If you are serious about buying it, then get at least two friends to buy it too because this game is made to test friendships and alone it isn't a real experience. I believe reviews that attack this game for being too hard are unreasonable, you are not meant to play it alone and neither finish a mission first try and you usually have to try 2-5 times until you develop the perfect strategy which then takes some time trying to execute it flawlessly. Due to this, the game is clearly not for everybody but for it's intended audience it's a really great experience!

As someone who loves a difficult game, doesn't mind dying hundreds of times perfecting a strategy, and has a group of friends to play with who like the same type of game?

This game is actually garbage. I love the concept, but too many features push it from "challenging" to "frustrating". To add a little context for those who haven't played yet, the game is all about resource management. The general game loop is sneak/stealth kill enemies slowwwly working your way to rooms where you bunker down to defend while doing some objective or other. Even the slightest screw up means wasting ammo or health, which will result in a slow painful death to attrition over the multi-hour long stages. The checkpoints are a good hour apart, and don't truly "save" so if you have to stop playing, you lose hours of progress.

The final straw where me and my friends put it down was after an hour of brutal slog, we got to the stage finale for the first time. This involved running through an entirely new section of the facility with a swarm behind us, sleepers in front, and a timer. A completely new scenario to the rest of the level thus far.

Of course, we died, we started contemplating a strategy to deal with it, but then realized the last checkpoint was over an hour back. We knew it would probably take us at least a few attempts to figure out a strat, which is bad enough, but on top of that eventually we'd run out of game time. Which means the next night we played we'd have to start from the beginning, get 1 or 2 attempts at the finale, rinse and repeat. Never touched the game again.

Only recommended if you have friends (even a single friend makes this game infinitely more enjoyable). Bots are brain damaged and prefer to shoot you over enemies.
