A fast paced, frantic action shooter that is similar in many ways to Left 4 Dead. Fairly cheap and fantastic fun in online co-op. Variety of levels and weapons. Only complaint is that the single player mode is quite boring. 8.5/10

An exceptional blend of Tower Defense and FPS. The game plays great and looks fantastic. Picture the art style of Borderlands, with the combat of Halo and the gameplay of Defense Grid. Sure, there aren't too many maps at all however, now with 4 player co-op and a decently long campaign that is very replayable and a blast to play through. Remeber, it's only £10. (9/10)

The origin of the infamous Half Life series. I personally feel that the series is a little overated but it's still a fantastic game and series. 9/10.
