I dont think I've played a game, especially an FPS , recently that I instantly started playing the singleplayer campaign AGAIN right after the end credits.

I have now. The sheer amount of freedom in the first few hours is awesome. There are soo many ways of doing things. Stealth, shooting shit up. Blowing shit up. Driving and blowing shit up. Hell even punching shit up and throwing things with super strength (Where anything is a weapon including a thrown sauce pan into a korean soldiers bollocks)

The amount of damage you can cause to some buildings is mental. I was buried alive in one once by a helicopter. Awesome weapon addon system (grenade launcher to guy in toilet ftw)

Also blowing a petrol station up was insanely impressive. Especially when it flipped a Korean tank. This game is soo much better than Farcry (which was a nice try but flawed) I even liked the Alien bits (though I had to lower shader quality for the ice bit) The aliens are very weird and with some seriously odd weapons but it seems like they are far more intelligent than it seems.

Awesome war with the Koreans bit (but it never called them South OR North Koreans as memory serves) particularly when I was doing super jump pistol dance round walls.

Lots of awesome guns,and not enough Koreans.

Big system requirements though... test the demo before you buy...
