ZOMBIE-VIPERS are COBRA infantry troopers who have been given a mysterious chemical substance, Compound Z, that has turned them into drones. Wiped of all thought, they follow orders mindlessly and cannot be reasoned with or sidetracked. They have retained their skill in combat; in fact, their desire to fight has been increased, making them more dangerous than before. In other words, they are deadly zombie warriors.
