This is really a very awful game, and it looks like it's been made in 2003. It's certainly not worth the price at all, and offers nothing special from the mainstream games. It's a real time strategy game where you can control extraterrestrials, UFO's, humans, tanks and even more. The idea is quite great, but the poor graphics and mediocre game play ruin the game completely for me. You should make your own decision of course, but I wouldn't recommend you this game at all.
