Treyarch's Zombies mode returns in Call of Duty, reimagined as a large-scale extraction mode decorated with the undead in Modern Warfare 3. Instead of using the standard field upgrade equipment found in multiplayer, Zombies mode uses its own unique set of field upgrade options. Here we list all the available field upgrades found in MW3 Zombies and recommend some of the best options for your match.

Field upgrades explained

Instead of the typical multiplayer options, field upgrades in Zombies provide a temporary elemental ability that goes into a brief cooldown. These will be familiar if you played Black Ops Cold War Zombies. There is only one field upgrade option to start with at launch, and more upgrades are unlocked by leveling up through the player ranks.

Energy Mine

The Energy Mine field upgrade spawns an explosive, dealing massive damage to enemies who set it off. This field upgrade has a medium recharge rate.
