Well I got this game for free a while back, and all I can say is what the hell. I mean, it's pretty fun and also my type of weird... You're killing aliens... Listening to fast paced rock music and the colors in the game are vibrant and neon. Enough to keep you hooked, but uh there's nothing more to it... It's pretty easy but the game has different difficulty levels to choose from. I can't say for sure or not if I recommend it, but for free, sure... Why not? I wouldn't pay more than .50 cents for it though.
