Last Updated on: 9 January, 2024 | 10:55 AM

Missions are one of the most important parts of COD games. No matter which Call of Duty game you have been playing, you can’t progress without completing missions. So, this is the same with MW3 Zombies. The most exciting part of the Urzikstan map is the DMZ elements. If you have played Warzone 2’s DMZ mode, you’ll remember the faction missions. MW3 Zombies features missions in the same way. Instead of factions, here the missions are divided into different acts and tiers. The more you go up these acts and tiers, the more tasks will be tough. So, naturally, you may need some help to know how to complete the Infiltrator mission in MW3 Zombies.

Before going to complete any mission, you must know that missions will help you understand the story and progress through it. As you complete new missions, new avenues will open for you to explore the story. Anyways, before we jump into the Infiltrator mission, let’s have a look at the objectives.

What is the Infiltrator Mission in MW3 Zombies?

As you progress, you will find different story missions on the map. These missions will give you a clearer understanding of the map and the story you are trying to explore. Among the story missions, the Infiltrator mission is one of the most straightforward missions to complete. The objectives of these missions are pretty easy to complete. The objectives are as follows:

Acquire a Stronghold keycard
Clear a Terminus Outcomes Stronghold
Retrieve Terminus Outcomes Record from the Stronghold safe

These can be the easiest tasks a mission can offer. For veteran players, it takes only a few minutes to complete these activities, but that’s not the case for newcomers. Also, some zombies make these activities a lot more difficult.

If you are new to Urzikstan and are confused about completing these objectives, don’t worry. We will explain all of them in detail.

Steps to Complete the Act 1, Tier 4 Infiltrator Mission Faster

Before you dive into the mission, first, make sure you are well-prepared for it. This mission can’t be done in installments. Once you start, you must complete all the tasks in one go. As an Act 1 Tier-4 mission, this may not be as simple as it seems. Zombies will be all over there. However, first, you need a Stronghold Keycard to start with the mission. Stronghold keycards can be found by clearing a Mercenary camp or a Mercenary Convoy. These can be located randomly anywhere on the map, but we suggest locating one in the low-threat zones. This will make things a bit easier.

Once you find a Mercenary Camp or convoy, travel to it and wash out the zombies and other AI enemies. This is a lot more difficult to do than say, especially if you are a newcomer. Fortunately, the enemies in these locations are not high-tier enemies. So, you can deal with them, even if you have to struggle a bit.

After you clear the area, a chest will be found at the center of the location, containing the Stronghold Keycard. If this method doesn’t suit you, don’t worry, go for the easy one, but that will be the expensive one. Find a Buy Station and purchase the Stronghold Keycard from there. It cost 2,000 Essence. The price is high but it will save a lot of time and effort.

The next two objectives of this mission will be done in a Terminus Outcomes Stronghold. Precisely, this indicates the most fearsome location to visit: Mercenary Stronghold. Now, that you have the key, open the map and locate the closest Mercenary Stronghold. We recommend finding one in the low-threat zone. Orange-marked areas are still okay but don’t go to the read-areas (Can check the above map location for reference). Strongholds already have uncountable enemies to clear, and if it is in a high-threat zone, the chance of your elimination increases rapidly.

Open the Stronghold door using the key, and start clearing the stronghold. When you are inside a stronghold, it is impossible to roam stealthily without anyone noticing you. Also, it would be best if you drilled a chest that will attract the attention of the enemies for sure. So, fight is an inevitable thing.

Generally, on the upper floor, inside a room, you will see the locked chest that you must drill to get the document that completes the mission. But the location of the locked chest differs based on the stronghold you have entered. Once you start to drill the chest, reinforcements may come. So, be careful to fight. Fortunately, the drilling process doesn’t need you to stay there. Once it starts, it will automatically complete, even if you are not close.

As the process is complete and the chest is unlocked the Cyperhead Tablet will spawn next to it. Remember, it won’t be inside the chest. For references, you can check the image above. Pick it up and the mission is done. But if you drill the chest and still don’t get the Cyperhead Tablet, it may be a glitch or someone has taken it before you.

What Are the Infiltrator Mission Rewards in MW3 Zombies?

Once you complete a mission after so many challenging activities, of course, the game won’t send you empty-handed. Like almost every other mission, the Infiltrator mission also has a few rewards to give you. They are listed below:

Raw Aetherium
Acquisition 3000 XP

You don’t need to do any additional activities to get them. As soon as you complete the quest, this will automatically be added to your inventory.

That’s all you need to do to complete the Tier 4 Infiltrator mission in MW3 Zombies. This mission can easily be completed solo, but if you are a newcomer, we suggest bringing a friend together. Otherwise, handling the strongholds will be almost impossible. If you die, the mission must be started from the beginning. Therefore, whether you can do it solo or not decide it based on your COD skills. One thing we can suggest is to take SMG or LMG rather than AR or shotguns. This will help you avoid frequent reloading.
