MW3 Zombies

The new Modern Warfare 3 Zombies mode is packed with story missions layered in different tiers for players to finish. If you are struggling with the Stronghold Keycard location, or how to handle the Terminus Outcomes Stronghold objective of the Infiltrator mission, we’ve got you covered.

When exploring the new DMZ-like Zombies mode in Modern Warfare 3, players will find themselves completing various story missions. With each Act, you will have to handle different tiers of short objectives that will require you to hunt some items across the map or kill specific enemies.

These missions are MW3 Zombies way of advancing the story on the Urzikstan map, unlocking a new cutscene every time you complete a whole Act. The new map has different contracts to complete and Strongholds to capture like in DMZ.

When working your way through Act 1 in Modern Warfare 3 Zombies, the tier 4 mission requires you to get a Stronghold Keycard and clear a Terminus Outcomes Stronghold. Here’s how to complete the Infiltrator mission in MW3 Zombies.

How to get Stronghold Keycard in MW3 Zombies

You will need the Keycard to access the Terminus Outpost Stronghold.

To obtain the Stronghold Keycard in MW3 Zombies, players will need to either assault a Mercenary Convoy or rush a Mercenary Camp. Both objectives can be found within Urzikstan’s Threat Zones 1 and 2, but the camp is more convenient since it is located in Zone 1.

MW3 Zombies features three Threat Zones with various difficulties, altering the Zombie’s health, damage output, and spawn amount. If you want to finish this quickly, take out all the mercenaries within the camp and you’ll find a Loot Cache near the middle. That cache holds the Stronghold Keycard and other useful gear like a 2-Plate Armor Vest.

You can also purchase the Keycard for 2000 Essence at a threat level 1 Buy Station, but it’s likely easier to assault a Mercenary Camp to obtain it.

Located in Threat Zone 1 when the Infiltrator mission is active, obtaining the Keycard will unlock a Terminus Outcomes Stronghold in MW3 Zombies. You will need to use the Keycard to unlock the building and clean up another one of these safe houses to complete the second part of the mission.

Once you kill every single mercenary inside, players need to locate the Stronghold safe, which can be opened like the Raid Weapon Stash contracts. This will signal enemy reinforcements, so get ready for another wave of enemies.

Killing every single enemy that spawns will clear the MW3 Zombies Stronghold and alongside the cracked safe, you will find the Cyphered Tablet. This tablet is the Terminus Outcomes Record you need to complete the Infiltrator mission’s last step.

Before exfilling from the map, check your Rucksack for the Cyphered Tablet and bring it with you, as this will complete the Infiltrator mission in MW3 Zombies. You will obtain a Raw Aetherium Acquisition, 3000 points of XP, and unlock the tier 5 missions of Act 1.
