Call of Duty's Zombies mode is back in Modern Warfare 3, with a new large-scale extraction format featuring the undead. In Zombies mode, you get unique field upgrades different from the ones in multiplayer. These upgrades give you special abilities with cooldown periods. Here's a rundown of all the field upgrades in MW3 Zombies and some top picks for your game.
Field Upgrades Overview:
- These upgrades are temporary abilities, similar to those in Black Ops Cold War Zombies.
- In the beginning, there's one field upgrade available, with more unlocked as you level up.
All Field Upgrades:
- Energy Mine: Sets off an explosive that damages enemies. Medium recharge rate.
- Frenzied Guard: Repairs your armor and draws enemy attention for 10 seconds. Kills repair armor during this time. Slow recharge rate.

Tips for Team Play:
- In a team, mix and match upgrades for the best combo. For instance, Healing Aura is excellent for group healing.
- Frenzied Guard suits aggressive players. It's useful in boss fights or to distract zombies from teammates.
- For solo play, Aether Shroud can be a lifesaver, offering temporary invisibility to escape tough situations.
In summary, choose your field upgrades based on your game strategy and whether you're playing alone or with a team.
