How to access all the Doom Eternal Slayer Gates for a special treat

Fancy a bit of a challenge? You can find Doom Eternal Slayer Keys tucked away in some of the missions and use them to unlock Slayer Gates. These challenges are intense encounters featuring tough waves of demons. If you happen to burn through your ammo and extra lives they are not replenished, making these a true test of your Slayer skills. 

There are six Slayer Keys and Gates in total and while these are hidden away, they’re visible as the purple circle and key-shaped markers on your map. Upon completion of a Slayer Gate challenge, you pick up a Doom Eternal Empyrean Key. Collecting all six of these awards you a special prize, and while we’re happy to help you out with the hard part of acquiring this item, we won’t spoil what it is.
