Heavy Zombies are an enemy introduced in Call of Duty: Black Ops Cold War in the Zombies map Die Maschine. They function similarly to normal zombies, albeit are much stronger due to the addition of much tougher armour, rendering a portion of damage negated until the armour is destroyed. This effect is combated by the utilisation of the Cavalry Lancer Barrel. The flags on their armour also indicates that they are of the Soviet Union rather than of the Nazi Party. This is likely that they are part of the Omega Group who were inside the facility, died and became zombies.
