Wow, Wraithlike you're not dead !
You got nice lookin' work there as I see. But since everything needs constructive critique than just useless posts....
Weapons Interface:
-mostly weapons got nice shapes and well used colors. They all got same color schemes so it looks very comfortable to the eye but some weapons are out of size. Like the MAC-10 looks kind of small, crossbow doesn't have good angle on that thing on right. G36 could need some work as well. Chainsaw got too dark gray in comparsion to the weapons-gfx.
Otherwise they're very tasty and I like the style very much. Many weapons are original and that's not really usuall to see. For example I love the spray-flamethower choice. =D
Game Interface:
-simple, nice lookin'. Nothing else to say. =) ...oh there is something, cursor rocks. =)))
Power-ups:
-nicely made, nice lookin' and I think they're clear to know which one is what. (Damn my english)
Gosteks:
-I can't really tell, because you made 4 ! =) Which is really cool, but some pictures to compare them could help.
Soooo, mod is very good lookin' and holds your standards. It is original with style and scheme so for now I lean back and shut up.
Good job.
