okay people this game should be rated alot higher, almost everyoe says oh this game is 1/5 because it loads slow don't rate the game bad if it has minior errors or it is slow from your own computer. please plus this so people do not under rate one of the best games and probaly the best shooting games.
I hope this game will get badges like 5 points for killing a total of 25 or 50 people. medium beat up to level 9 in human story mode. hard: beat human campain impossable beat both alien and human campains.
