hmm, i voiced a similar idea to shok earlier, but, i must say i think its a good idea for an idea. you would have to change it so people could carry three weapon types tho, your class weapon (and i would hope you would only get to choose between the normal weapons, like: rifle, sniper, AA, and shotgun), then of course you wouldget your pistol, and the third weapon slot would carry a weapon you just picked off the ground, which could be any other weapon except for the class weapons. ammo would be in ammo boxes, not found on other guns or corpses. yes, it would have a battlefield/battlefront feel to it, but i think it may work...
