To complete the Infiltrator mission in MW3 Zombies, you must achieve these three objectives:

  • Obtain a Stronghold Keycard
  • Clear a Terminus Outcome Stronghold
  • Retrieve Terminus Outcome Record from the Stronghold Safe.

1. Obtain Stronghold Keycard

The first thing to obtain is a Stronghold Keycard. These keycards can be collected from different mercenary outposts on the map. Or you can get it from mercenary convoys. It would be best to assault a mercenary outpost; some enemies might drop the stronghold keycard.

Besides mercenary outposts or convoys, a stronghold keycard can be collected from a Cache, or you can buy it from buy stations for 2000 Essence.

2. Clear A Terminus Outcome Stronghold

Once you have obtained the stronghold keycard, head to one of the Mercenary Stronghold on the map of Urzikstan. These are located in many places, so choose the one you are comfortable with.

Open the door of the mercenary with the keycard and kill all the enemies inside the Mercenary Stronghold. Once you have killed all the enemies in the building, locate the safe that contains the Terminus Outcome record.

3. Retrieve Terminus Outcome Reward

After killing all the enemies and finding the safe, you must start drilling the safe. This process will take some time, and during drilling, reinforcements will be called in the mercenary, so you need to defend yourself and kill the enemies until the safe is cracked.

You can stay close to the drilling, or it might pause until you get close enough. Once the drilling is completed and the safe is cracked, collect the quest item Cyphered Tablet. This will mark the completion of the Infiltrator mission in MW3 Zombies.

I recommend you find a spot near the safe while drilling and kill any enemies in the vicinity. This complete guide will help you achieve your Infiltrator Mission in Modern Warfare 3 Zombies.
