an instant classic and one that will be remembered forever as a true game-changer.
the only problems :there is no multiplayer(WOW imagine how fun that could be !) .the graphics are a bit too next-gen for their own good so you definitely need a high-end rig to be able to play it on the max settings.the developers haven't announced any DLC for it yet but don't worry , such a great game will definitely get more support in the future
so go out and grab this gem of a game(hell even buy two to tell your friends how RAD you are!) to support their developers so that we might see more unique games like it in the future.
what are you waiting for ? go get it already!
