With turrets scattered across Urzikstan, someone needs to go around and activate them to deal with the constant threat of mercenaries and zombies. That someone is you. Thankfully, all turrets are friendly to you and others in this PvE mode.

MWZ: Automated Backup mission guide

The Act I: Tier III mission ‘Automated Backup’ asks players to activate three separate Deadbolt Turrets using ammo mods. While Turret Circuits are in the game and can be found more frequently than others, these are not the correct items needed to complete the mission. Instead, players need to find a specific circuit titled ‘Cryo Freeze Turret Circuit.’

You need to find three circuits for three turrets to complete this mission in MW3 Zombies.

The best place to find and farm the Cryo Freeze Turret Circuit is inside Infected Strongholds. You must clear these as you would with any standard Aether Nest. You need to destroy every cyst within the stronghold to successfully clear the building. After you have done this, the spores and clouds will clear, and you are free to explore and loot up. Make sure to check every crystallized supply cache, as these will likely hold the circuit board you require.

While these are not guaranteed in every Infected Stronghold, they are by far the best place to check. Make sure you are specifically looking for the Cryo Circuit and not the standard Turret Circuit (both have a blue icon).

Whether you have found all three Cryo Freeze Circuits or are completing this mission one turret at a time, you need to make your way to a Deadbolt Turret. Look at the tac-map and zoom in for the turret icon. Set a waypoint using the ping system and head over to the turret. All you need to do is go up to it, interact, and select the Cryo Freeze Circuit. After placing the circuit into the turret’s compartment, close the pop-up screen to activate the turret.

Tip:

Make sure you are installing a single ammo mod circuit board on a turret, as installing three will not work for this mission as the tracker only registers a turret once.

The turret will come to life and mow down any enemies that are alert to your position. Complete this mission by activating three separate turrets using three newly equipped Cryo Freeze Circuits.

Rewards for completing Automated Backup in MW3 Zombies

As you come close to finishing the automated backup mission in MW3 Zombies, you’re probably wondering what the rewards are, read below for more information:

  • 1,500 XP.
  • Death Perception Acquisition perk.

The Deception Perception is a Perk-a-Cola perk in MW3 Zombies that allows players to have an enhanced awareness to locate nearby enemies. The Depth Perception perk is single-use but adds a huge advantage to your playthrough, and the additional chunk of XP is definitely an incentive to finish the Automated Backup mission in MW3 Zombies.
