MWZ: Automated Backup Mission Walkthrough

By asm3a November 21, 2023

Automated Backup is a mission in the third chapter of Operation Deadbolt in Call of Duty: Modern Warfare 3 Zombies that’ll have players praying for good luck. It’s not exactly a difficult mission, but it definitely relies on a ton of RNG just to get the items needed for its objectives.

Finishing the Automated Backup mission can take either no time at all or all the time in the world. However, if Call of Duty: Modern Warfare 3 players know what they’re doing, then they’ll be able to finish up this mission relatively quickly.

MW3 Automated Backup Guide

The objective of this mission is simple: use Ammo Mod Circuits on three different Deadbolt Turrets. However, getting the Ammo Mods for the turrets isn’t as easy as it sounds.

Ammo circuits imbue turrets with elemental firepower depending on the circuit players attach to them. These make turrets exceedingly strong for defending areas, and as one would expect, ammo circuits are also exceedingly rare. They can be found almost anywhere, though high-value POIs tend to have them more often.

For the best chance at getting ammo circuits, players should hit Aether Nests and Infested Strongholds. Raiding these POIs can be very dangerous, especially for solo players. It’s best to come with a pre-made squad or ask other players on the map for help.

Looting nests and strongholds will not guarantee an ammo circuit drop. However, they tend to have the best drop rates among all the containers. To clear these areas, players need to find and shoot all the cysts growing on the walls. Zombies and poisoned air will complicate things, however, so make sure to bring a big gun and a couple of gas masks.

Once players find one ammo circuit, they can use it to power up any of the Deadbolt Turrets on the map. They have their own unique icons, so they shouldn’t be hard to spot at all. Approach a turret, interact with it, and deposit the ammo circuit to make progress with the mission. At this point, players will have to do the entire process two more times. Luckily, this doesn’t have to be done in a single run.

Regular ammo circuits won’t count towards the objective. Players need to find Ammo Mod Circuits, ones that grant effects to turrets like Shatter Blast, Cryo Freeze, and Brain Rot.

Completing the mission gives players a free Death Perception perk as well as 1500 XP. The perk can be found in the stash’s Acquisitions tab once players are done with the mission. This can be viewed by selecting an empty bag slot.
