Well at least one guy who knows my battlement stealth tactics in ZS... One more thingy that i came up to... Engineer manual controlling turret, well its not a turret its a moderate barricade (that needs much of free space, to prevent from cading) with a gun mounted on the top (with unlimited ammo) (just like Combine pulser mounted on the Force fileds in HL2). Only your squad can use this one. The higher lvl you get the more powerful it will be. Flashbang for commandos? Well yes, it can get nerfed, but also "sometimes i dream about flashbangs when zombies are near about to rape my ass", and oh yeah it will be the 1st nightmare for zombines. Act like with engineers: flashbangs cannot flash humans, only zombos.
