I'm looking for a game to get for myself and some friends (late Xmas gift, ftw). I want to get something that we can all play together, so co-op would be best. We have L4D2 already, so that wouldn't be something I could get again. Ideally it should be 4+ player co-op. We normally play games like Battlefield Bad Company 2, Uncharted 3 and Pixeljunk Monsters. I could really use some suggestions for relatively cheap (old too is fine, some of my friends only have laptops to game on) games that are available ideally on Steam and that would suit our tastes.
So help me out VGChartz, what can you suggest?
