I must agree with everyone saying that the alien campaign is cheap. Most of the time when you win it's purely luck; your friends managed to not die long enough for you to actually get some kills in. I like this game, but the later levels in the alien campaign are just rigged.
Great game, but the AI seriously needs to be rebalanced. I hate having a raze soldier spawn on top of me (about a dozen times a match) shoot me at close range with a rocket, and then I die, but not him, because he still has invincibility from the spawn.
Ahaha thanks :3 me and my other mates all chucked in a meme/game reference in our games for lulz
