Bio-Suit Zombie

The Bio-Suit Zombie, also known as a Hazmat Zombie, is a monster included in Doom 3: Resurrection of Evil.

A Bio-Suit Zombie fights just like the normal zombies do, by clawing at the player when they get too close to them. When killed, a Bio-Suit Zombie will drop their enviro-tank, which gives the player extra time to be safe inside toxic areas.
