To unlock the Unmaykr in Doom Eternal, go down into the depths of the Fortress of Doom (check out the images below to see where to go). Press the button in the center of the machine to use all the Empyrean Keys you’ve already collected. Once you use all six, you’ll unlock the Unmaykr, and you’re gonna love it.

The gun really lives up to its name. You switch between the BFG and the Unmaykr by pressing F on PC (and whatever the equivalent is on your console; the game will tell you what to press).

Slayer Keys Not Appearing Bug in Doom Eternal – How to Fix?

To fix the “bug” in Doom Eternal where the Slayer Keys are not appearing, you have to check if you’re using cheat codes. If you are, that’s your problem. The Slayer Keys will not spawn if you have the cheat codes on. You have to turn them off manually before attempting to replay a mission. Also, even if you’re playing a mission for the first time, where cheat codes can’t be used by default, it’ll still see them as on. So, make sure that you turn them off manually. If that doesn’t work, you might have to restart the game to fix the problem.

    Just trying to figure out why i can’t pick up the keys? I’m playing on normal difficulty and on my first run through the key did not spawn. so i reloaded the level thinking many that could be the issue but still no key, i have tried this on the first 2 locations for keys to no avail. Any suggestions on what i am doing wrong? Playing on Xbox1 preorder basic edition

      Had a similar problem, so from the doom slayer ship i reloaded a level but made sure to toggle all cheats off. Even if i used cheats before, starting a brand new level would prevent me from getting the keys.
      Might be a weird glitch by it isnt to difficult to fix
