A hilarious horror game, as ironic as that is, blending Valve's perfect humour and atmosphere into one brilliant, action-packed game. The game controls so nicely and is a good challenge on normal difficulty and has excellent characters (in both sets of campaigns). I haven't played the other modes, but I bet they're a blast judging from the main game. Definitely one to play with friends; you'll be missing most of the fun of the adventure otherwise
