The game is dynamite its brilliant. Me and my friend have reviewed this.
Graphics: over average pretty cool. The graphics make you want to play on with stunning effects.
Gameplay: This has got to be one of the best first person shooters of all time. The guns are not superbly realistic but they are good enough. The missions are very exciting and are hard on some parts of the game.
Sound: The sound has nice effects and are really nice tunes that get stuck in your head.The zombie effects are pretty good.
altogether my friend would give this a 89% out of 100% (personally ide give this a 87% out of 100%).
