- "Basic zombies have a chance to explode when killed, leaving behind a contamination field that slows enemies and increases damage dealt to them."
- — Description
Zombshell, when purchased, will allow players to have a chance to create a small contamination field when killing normal zombies. This field comes in the form of a small electrical orb, which will last for between five to ten seconds. When a zombie comes into contact with the field, they will be slowed down, and any damage they receive will be increased. Once the orb disappears, the perk will recharge for roughly 15 seconds before its effects can be activated again.
When Zombshell is set as the "Modifier" perk and the player has all of their other perks, the perk will allow players that have the perk as the modifier to be ignored by zombies while standing in the contamination field, similarly to the camofluage effect of Vulture Aid from Call of Duty: Black Ops II.
- The name of the perk is an abridgement of the words "zombie" and "bombshell".
