Good
the game is so fun but short but i think that you will have a great time playing i don't even see why this game so much bad rating it should have got more then it really did the rating were bad because the game play was short but fun the graphics were great the game has some realistic stuff and some not realistic stuff like when your in the rain the drops will bounce off your gun and that's real but in one part they made a general walk a robot . the driving controlling r like halo . the game is not just about shooting aliens first level you shoot soldiers then you shoot mutated humans and animals then later you shoot aliens and mutated stuff the game is about area 51 is a base hidden the hills you don't find any aliens testing there it looks like a military base then there was secret place that Rome and area 51 have testing humans that worked perfectly until it got out of hand so the government decided to close it down but the mutants got free so they started war somehow aliens come by and you and a elite squad has to go bye and kill them i would rate 10 but online wont work unless router into a curtain code but buy the game and enjoy

good Game
exciting Game and good price !
