How to Increase Contraband Stash Size in Warzone DMZ

Your loot, your stash.

Players’ Contraband is exceptionally valuable in DMZ, whether it’s rare items they’ll come back to or equipment needed to progress and complete objectives. It’s frustratingly small though, which is why you can expand it. Here’s how to increase the size of your DMZ Contraband Stash in Season 4.

Upgrading Your Contraband Stash in DMZ

Firstly, you’ll need to locate the Upgrades Menu within DMZ itself. Click on ‘Mission Objectives’ from the lobby screen and move to the right one spot, and you should be on the Upgrades Menu. 

You’ll see options to upgrade your Wallet as well as two Stash Expansion options. The first is the general Stash upgrade menu, the one further down relates specifically to the Crown Faction. Both are useful and offer tangible and obtainable benefits to the amount of extracted equipment and Keys you can store.
