I just downloaded the demo a couple days ago on Xbox Live and holy crap i have been having TONS of fun. If you haven't downloaded the demo i would suggest you give it a whirl. The Frostbite engine that its using makes environments completely destructible. I was playing last night with a couple friends and i got trapped in a building with a tank watching the front door trying to kill me. No sweat, i just toss a grenade against the back wall and blow a hole through it and i go out the back.
