Single and Multiplayer games are simply awesome. In Single player you play The Marines, Aliens and Predator. It's great how they mixed these races up. I don't really want to say much about the missions or the story but it's still great. Multiplayer is really great but I never played online I always played through Lan with my bro' and we just played as the marines fighting against a horde of Aliens a really kl mode and I still love it. Graphics aren't trhe best but I think having Polygons to produce Aliens and Predators are really kick ass. There isn't much to be said about sound. Gameplay took me a while to get used to the keys since they do varie on the keyboard. Tons of Value you got 3 races to play in each of their single player game and the multiplayer
