easily some of the best fps I've played, super fast, super short but give you an amazing well made campaign along with some incredibly fun traversing mechanics and brilliant set pieces in each levels. Even when the campaign is really short the game does a good job at establishing the relationship between cooper and BT. It's constant action with very few cutscenes and each level introduces you to a new weapon or ability and keep up at that fast paced action going. Playing this on the master difficulty isn't fun all the time but I still enjoyed it for it is.
