In this game there are three different campaign. One each for Colonial Marines, Predators and aliens. The alien is the most fun one and it feels good to crawl around in the roof and drop down on the defenceless humans as they scream in fear. To bad that the game is so short as it only contain the standard number of first person shooter levels split in three parts.

Worse then the first game. Short one way level and even alien style is boring :(.

Nice but stupid AI on the marines really destroy the game. It's no fun to stalk the humans as a alien when they are to stupid to even notice that someone dies right in front of them. Then when you play as human you have to suffer with them repeating the same stupid line of dialogue the whole game. The three way story do not really work that well also, minor point really but when you play the whole games it would be nice for it to be good.
