Unblocking Unmaykr is not very complex but to do that you will have to prove that you are a real Slayer. In fact, the weapon rests inside the Fortress of Destiny, the Doom Guy space base (a few rooms beyond the command station), and can only be unlocked after collecting all 6 empyrean keys.

These keys, in turn, are the award of Slayer Challenges, of particular battles marked with a purple zone on the game map. To access it, you need to open i Slayer gates and with a Key Slayer, hidden in the vicinity of the gate.

Empyrean Key 1 | Mission 2: Exultia

Towards the end of the mission you will notice the Slayer gates on the right of the map in the center of the large purple colored area. To open them where to collect the key located on a platform just above the gates.

Enter the cave a little further on and climb the raised rocks until you reach the space above the cave exit. Turn around and you will notice an opening above the entrance as well. You will have to jump and reach it thanks to the clickBut rest assured, the floating yellow capsule will recharge it in flight making things even easier for you. The key is on the platform just below your position.


Slayer Challenge 1

A very simple challenge in which you will have to eliminate all enemies in the area. The combat area is narrow, so if you have upgraded the sticky grenades you can try to gather the enemies in the corners and blow them up with a single grenade. The only ones to watch out for are the Tyrants that appear towards the end of the challenge. These could really get you in trouble but if you keep the Fist of Blood and use the grenade tactic you could even take out a couple of them at the same time.


Empyrean Key 2 | Mission 3: Follower Base

Also near the end of the mission you will arrive in a circular area with a crucified demon. Here you will find the Slayer gates, but to reach the Slayer key you will have to go through the following platform section:

  • Go behind the crucified demon and jump to the scalable wall at the bottom right in the abyss;
  • Turn around and look down to the right to find an opening with two yellow bars;
  • Use them to continue and get ready for one series of jumps (remember to use the trigger, there will also be yellow capsules that will reload it in the air);
  • When you get to the climbing wall at the bottom, climb to the top and jump back to take the Key Slayer.

Slayer Challenge 2

A more complex challenge in which you will be attacked in multiple waves, as well as by simple enemies, also by Aracnotron and Mancubus. Fortunately, the former can be knocked out by breaking the sweet spot on their tail, while the latter are so big and fat that they are a good target for the rocket launcher. If you have any problems, remember that you can use X to saw smaller enemies in half and get ammo, armor, and life.

Empyrean Key 3 | Mission 5

Towards the end of the mission, the Slayer Key to open the gate is found near a Sentinel Battery and the procedure for reaching it is the same. Jump onto the blue energy flow and once up, sprint right over the wall to enter a new area. Go all the way to find the key and battery.


Now you just have to reach the Slayer Gate a little further in the area with the colored pedestals.

Empyrean Key 4 | Mission 6

This time the key will be found in the first part of the mission shortly after encountering the first Mod Bot. After the area with the escalators you can find the key in a room just above. Use the wall to reach it.

Empyrean Key 5 | Mission 7

About half level. To reach it you will have to enter a small room with many tentacles and interact with the device to operate the platform in the distance. Jump to the platform on the right and punch through the frail priest to reach the key.

Empyrean Key 6 | Mission 9

The last key is after the second swimming part of the level. Take the corridor to the left instead of moving forward to progress the mission. The Slayer Gate will automatically open to give you access to this latest challenge.

Once this is finished, you will unlock the achievement trophy Destroyer of Gates, as long as you have opened all Slayer gates in the same save.
