DOOM Eternal - Unmaykr Storage

The Unmaykr can be unlocked in the game by completing 6 Slayergate challenges.
In the Fortress of DOOM, upon completing these challenges, you can use a 'key' won from each challenge to unlock an element on the case. Once you've completed all of them, you get a cool weapon!
