Holy crap, this is a very cool game! I played the demo on Steam using my Macbook Air and it plays extremely well. It reminds me a lot of Gears of War. I know that the MacBook Air is not supposed to be a gaming machine, but this demo is awesome. Has anyone else tried it and have excellent results as well? I am running around 1280 x 720 with medium settings and it is very smooth. I was wondering if the new Deus Ex game is optimized as well as Warhammer? I am thinking about getting this game, especially since you cannot find another GoW on the PC.
