Modern Warfare 3 Zombies mode is full of DMZ-like missions with different tiers and objectives. If you are struggling to find ammo mod Circuit Boards, or can’t find the Deadbolt Turrets for The Automated Backup mission, we’ve got you covered.

There is a lot to do in Modern Warfare 3’s new Zombies mode story and to complete each Act mission, you will need to find certain items scattered across Urzikstan. Some of these missions not only require obtaining the items but also taking them to specific parts of the map.

In Act 1 tier 3, players will be tasked with tinkering with the Deadbolt Turrets found in Urzikstan’s different Threat Zones. If you want to finish The Automated Backup mission and follow up on your story quest in MW3 Zombies, you need to first claim the ammo mod Circuit Boards.

Here’s how to complete the MW3 Zombies The Automated Backup mission.
