I don't like it that much, downloaded it in about an hour..
It's would've been better as a FPS based game, like Halo only with thousands of insurgents,
game play is slow and methodical, the intro level takes forever to get past and I got frustrated after about 45 minutes of just telling guys in Warthogs to go from Point A to Point B then having to avoid the Covenant b/c I didn't have gunner active yet the only attack I had to was just try and run things over lol
