Gamespot has posted some impressions from Xbox version of Counter Strike. "We got to play on three maps: Dust and Italy, which should be eminently familiar to longtime CS players, and Vostok, a snowy demolition map made especially for the Xbox game (of the 20 maps that will initially be available, seven are Xbox-exclusive). The two old maps played very much like their PC counterparts, though they looked a lot more detailed. Cliffe pointed out that the Xbox version uses 24- and 32-bit textures instead of the 8-bit palettized ones found on the PC."
