great game i have had fun while playing a shooter in a long time. even though that it does slow down a liitle bit but you can notice it very much. the only time that i have notice a slow down is when there was to much action on the screen. or when when there a lot of enimes on the screen that is it. the graphics or not that bad. the controlls to me awhile to get used to but they were not much of a problem. the only problem that i had with game is it does not have multiplayer or counterstrike source and mods. ithink that valve did a great job by converting a highly demanding pc game to the xbox is tough but they pulled it off.
