Right lose the installer, there's no need for it. As it's quicker to copy and paste and the install takes 5min's on the unistall thing. Also no need for that. The Colt for allies had no reloading sound. The M16 works great, the M14 sniper has a funny sounding shell when it hits the ground. The M60 works great, the only gun with sufficient amount of extra clips... The Grenade Launcher is awesome. For the Axis the pistol and grenade are great. The Dragunov however doesn't show up, I love this weapon so it'd be nice for it to work. The RPD is good. The RPG is good. As for the ambush level is good. But the assault level (the obj one) has major problems. Like tom said the helicopter is floating in the air with no visible means of support. Also you can walk off the edge of the map and into the skybox. And the lighting on both is not that great it is too bright and seems cartoony. Other than that the modeling looks good (execpt for the dragunov, which is invisible).
You really should lose the installer because some people, like me, where afraid it may contain some virus. I guess it would be handy for non-mappers...
Also give the player sufficient spare clips....
I don't mean to be critisizing just a little constructive critisism. I know this is just the beta and I'd love to see the weapons working, as I love these newer guns...
