Achievement Unlocked 2
Achievement Unlocked 2 is primarily a game of random achievements that you can unlock by going through the different scenes. It pokes fun of gaming sites and games in general and the "achievement based" gaming culture that's cropped up over the last few years. You can play single player or co-op, and there are time trials to see how many achievements you can get in 4 minutes. Or you can play Free Play, which is like a campaign mode. You'll hit achievements like "Dizzy", "Corpse Juggling", and "Soggy Pastries". Yeah, it's pretty ridiculous but it's loads of fun!
