9.0/10 This is a very well done first person shooter (FPS) with an in depth story line. There are lots of cool weapons and the enemies have fairly descent AI. The environments change throughout the game so it doesn't get boring and you can interact with people which is a rarity in FPS. It is a descent length at over 25 hours to finish. What really makes this game awesome is the multiplayer capability which is very fun as well as additional levels you can download that other gamers like yourself have built. And if your feeling brave you can even design your own levels!
