Well I bought the game and frankly it was an astonishingly good looking game even though it is based on the venerable Unreal Engine. Only gripe I have is that the game is quite short. Need more levels.
The graphics @ 1280 x 1024 on my laptop brought the GPU to my knees when there was a lot of smoke and particle effects. But the game was released for SM 1.1 or 3.0 and so us ATI users with 2.0b capability were hung out to dry which is what I really disliked. I am sure with the 2.0b support, if the game had it it would have probably run better @ the same res or even higher and looked a hell of a lot better. Been tempted to buy an Nvidia just so I can play the game on the dekstop in all its 3.0 glory. But I resisted since ATI is launching their R520 soon....all in all it was fun. A 9 out of 10.
