Hey, a free game, it wins in my books. It wasn't even half bad. I enjoyed the T-Rex campaign and how they kept adding more cybernetic parts to it, gave me a good chuckle. I got all 200, played the multiplayer game by just plugging in another controller and that was it. Once again, can't complain about something that was free...and fun!
Edit: The same night I downloaded this, I also downloaded Aegis Wing which is pretty fun as well. Two free games in one night, free gamerpoints for everyone, whats not to love!?
