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.
Here I write what I think about the games I have played. The score is shown as a smiley before the title of the game.
Note about Movies: None of the Youtube movies that i link to are made by me and i include them only to give you a chance to see what the game looks like. Only the text and the smiley score act as my review of the game .
