I like FPS and and am not a particularly demanding consumer - but this game is literally unplayable. I loaded the game and got through the training section and then at the start of the first scenario my PC (Dell XPS P4, 1gig memory 6800 video card) locks up completly and needs to be physically switched off and on. Irritatingly enough it's not at the exact same point each time but always within the same area. I downloaded the patch (100mb) and it still hangs. I have uninstalled and reinstalled several times to no avail. If you do a google you will find that this type of problem is not uncommon. It's a shame as it's a great premise but there are other games out there which actually work!
