I'm only getting you back cause you reviewed mine :P
first impressions, lighting fits well, textures are effectively utilised for their purpose, envmap entities are placed, the geometry overall is rather interesting
though I have to criticise you on keeping such huge open spaces (you know which ones I'm talking off, outside the windows where there's rain :P). and on the geometry too, in several instances it seems a bit "flat" or undetailed.
while I didn't play with anyone yet, I'll still commend you on the powerups not being very easy to get to, and the weapons appearing to be well spread out.
overall, good job, I'll give you a 0.8 (think of 1 = 5/5 :P)
