suicide zombie

a suicide zombie will often take out a live grenade and attempt a kamikaze-style attack on their prey, rushing towards them until the grenade explodes, killing the suicide zombie and damaging the objective. When suicide zombie attempt to use their grenade attack, they will start to walk when their grenade is stolen from them.

If the suicide zombie pulls out a grenade, it is best to run back and allow it to explode. However, this may not be the most effective tactic, as they will generally run after the player.
