This mod introduces the hazmat outfit you wear on Call Of Duty: Black Ops 1 Campaign and Black Ops 2 Zombies when playing as CDC.
Custom glove usage is allowed, but no masks since you are wearing a whole hazmat suit.
Warning: I tried to disable masks but it's a 50/50 if they still appear or not, so I recommend downloading this mod to get the full no mask experience.
Some clipping may occur with the neck and the hazmat suit if the character bends their head/neck too far down, up, left or right but will be fine if their head isn't too bent
Have you thought about making the hazmat headpiece a seperate mask? Would help with any heisters with huge hair (i.e. Jimmy)
