Anyone remember Damnation? There was an Unskippable for it, and it received a metric fucktonne of bad reviews. I picked it up on Steam during their last big sale just because I wanted to play some weird FPS (I also picked up Chrome, which sucks balls).
Oddly enough, this game is actually pretty good. Yeah, the production values aren't the best in thw world. But if you want a game that takes Assassins Creed, Unreal Tournament, Call of Juarez and smashes them together, then this is it.
The gunplay is pretty bad, and the main fault of the game. But all the platforming stuff works so well I wish other games tried it. The AI is poor as well, but the different (not necessarily great) story along with the aforementioned platform elements and steampunk motorbike bits more than make up for it.
I'm say what other FPS games I prefer it over, but I'd get lynched for it. It's cheap and good. Although not good enough to crack into my top 5 of Far Cry 2, Crysis, UT2004, Tribes Vengeance, Mirror's Edge (I wish I had room for TF2 in there but it's gone down such a bad path).
