Slayer Gate

Slayer Gate is a new feature in Doom Eternal that provides optional, but intense, encounters.

There are a total of 6 gates, and each one needs to be unlocked by a Slayer Key that's found near its respective gate. Completing all 6 gates will unlock access to the Unmaykr in the Fortress of Doom.

Choosing to play in these areas should not be taken lightly, as ammo and extra lives that are spent in a gate will not be restored afterwards. However, completing each gate awards 3 Weapon Points and an Empyrean Key (all 6 keys are needed to unlock the Maykr Device where the Unmaykr is locked).

One can encounter Empowered Demons here, which are demons that are periodically empowered by the Khan Maykr if they killed another player in the campaign. This makes them stronger but also drop extra resources when killed. When they appear they'll have a notice above them of the player's name they killed.
