With the release of the Warzone Season 3 update, players can earn an array of free rewards, and one of them is the Welcome to the Mainframe camo.

However, as is tradition, you won’t get this cosmetic reward right away, which means you have to complete a certain task or a set of challenges to get your hands on this weapon skin. 

Therefore, here’s a quick guide on how to unlock the Welcome to the Mainframe camo for free in WZ Season 3.

The only way to unlock the Welcome to the Mainframe camo is by interacting with a Biometric Scanner on Rebirth Island for 27 days. These scanners are scattered across different locations on Rebirth Island, and we will also discuss their exact spots later in this article.

You can get a new cosmetic reward every day by using the Biometric Scanner. On the 27th day, you’ll unlock the Welcome to the Mainframe camo. Don’t worry, you can miss some days and still get the reward.
