oh you haven't? you really should... I'm sorry I hate it myself when people say things like "You have do that", but still it's a great game... simple though, but the characters are funny and it's totally obsesive.
Yeah. I think it's for... xbox too but I'm not sure. You can buy this "orangebox" thing with ... portal, tf2 and halflife games(all pc). My bro bought it and that's the only reason why I'm playing it. His friends tend to get a bit confused though.
