If you’ve been taking on those Infested Strongholds or Aether Nests in MWZ, your Gas Mask will undoubtedly be close to breaking, and you may be looking to pick up a new one. However, you can actually keep your original, as there is a way to repair it!
Gas Masks are essential, especially if you like to wait until the final exfil. A full mask could be the difference between dying or surviving if caught in the storm.
So let’s dive into how you can repair your Gas Mask to loot effectively and ensure you don’t die to the Aether storm.
How to Repair Gas Mask
To repair your Gas Mask in MWZ, you must replenish your ammo at an Ammo Cache. Whenever you get ammo from one of these locations, it will also bring your Gas Mask back to 100%.
Ammo Caches can be located by looking for the icon shown in the image below.
This trick is even more beneficial if you have a Durable Gas Mask, which is harder to obtain than a regular mask. This means you can keep repairing it so you do not lose it.

Repairing your mask can be done as many times as you like. It could also save you tons of Essence in the process, as buying Gas Masks in MWZ costs 2,000 from Item Shops.
Watch the video below and notice the Gas Mask durability go up when you replenish your ammo at an Ammo Cache.
Now, you can make a one-time purchase and have a Gas Mask for life! That is if you can successfully exfil each game with it.
You can also make the most of your replenishable Gas Mask by looting Aether Nests and Infested Strongholds.
These locations can contain lots of valuable loot, and having a mask is vital to clear them out effectively.
