Heavy zombie is a playable zombie character in Zombie 2: Mutation, Zombie: The Union, Zombie 3: Hero and Zombie 4: Darkness. It also appears in Zombie Scenario and Zombie Shelter as AI-controlled NPC.

Heavy zombie appears in all chapters of Zombie Scenario.

- Double Gate: Crasher-type Heavy zombies (blue-skinned) make their first appearance in Double Gate chapter hard difficulty. They are hard to be killed due to high health points and deal high damage to the gates and humans.
Zombie 4: Darkness
- New sounds have been added for him in Zombie 4: Darkness as well as a new appearance.
- In Zombie 4: Darkness, the heavy zombie has the ability to stomp the ground, and also increase his defense (more stun and knockback resistance) but at the cost of mobility. However, he loses his 'Trap' ability.
- Becoming a Heavy Zombie
- A message will be displayed everytime a human has been caught in a trap along with a HUD indicator to show where they are.
- Turn around and move backward in ducts to face humans to avoid being shot in the head.
- Engage stationary humans as they are easier to get to because of the high knockback and stun resistances. It also helps your teammate to act as a 'tank' to block damages because of your high defensive power.
- Set traps in common areas such as ladders.
- Crouching might reduce the possibility of being shot in the head.
- Unlike most of the zombies, the Heavy Zombie poses a high defense and can take more shots to take him down, even without any armor points left.
- Facing a Heavy Zombie
- Do not engage the heavy zombie alone as it will drain all your ammunitions to maybe even kill him, unless you're using powerful weapons. Also, you might get ambushed by other zombies before the heavy zombie die.
- Do engage when there's other teammates attacking him.
- Check for nearby traps whenever you move. Remember that the trap can move by itself, so be careful.
- Heavy Zombie has 2700 health points (3200 with Strong Lifepower).
- Heavy Zombie can ensnare both Humans and Zombies of the opposite team. Any target that fell onto his traps will be unable to move and have their health reduced.
