Fucking love this game. Has really god-tier atmosphere, interesting stealth/squad gameplay, good sound design, decent humor and an ok story. The graphics are kinda shit but they have their charm, and I suspect the animations are simple and models are low poly since the game needs to render itself 4-5 times.
That being said it's hard as balls and really weird to play. It actually reminded me what it was like to play video games for the first time again. It's a lot like Thief, where stealth feels like the most viable option, not so much something the game forces you to do. You have to manage a squad, each in first person, which is easy enough unless you're in combat. If you get caught though it's overload and really hard to manage. Not to mention every level has a way for reinforcements to show up unless, so gunfights are usually a losing battle.
Also another thing I appreciate is that the levels very a lot. First one is exploring a town, second one is exploring a city with sewer/rooftop access adding a 3d element, next one I believe is a road you have to go along with army trucks driving by (if they see you they will drop off troops and you can get in an infinite loop of trucks seeing you in a gunfight and dropping off more troops), etc.
It's not for everyone, but it's right up my fucking alley.
