List of completely repetitive and mostly useless brutal doom things:
MP40(same as smg)
SMG(another rapid-fire weapon)
Machine Gun(just rifle rocket/grenade launcher combo)
Pistol zombieman(slower overall worse bd zombieman that could easily be replaced by having a normal zombieman occasionally drop a pistol)
Zombie scientist(fodder pinky that does less damage)
Mummy(Pinky with even more health)
By most people and myself these monsters add flavor to the mod, but from what you just said, all of these are redundant.
