How to get the key and the door of the killer on Cultist Base in Doom: Eternal

Slayer doors are extremely difficult meetings doom: Eternal. In them, you are transported to another reality where you fight against a wave of apparently endless demons using the ammunition and the extra lives you have on your person. If you do not have enough, you recharge at the next checkpoint, and sometimes you get out with barely the balls. However, you must complete them all to complete the demonic corruption counter and unlock a final weapon.

You can find a killer door towards the end of the mission of the cultural basis. It's just before using the train to enter the terrordome to kill one of the priests. You find it in the room where you have to slaughter the giant statue to break a hole through the wall and use it as bridge to the next room. You want to shoot the statue before going after the killer door.

After shot the statue, try to dig on the left of it. You should see a wall you can enter if you run away. Do it and enter the wall. Look behind your position to see a yellow bar. Double, but hold your dash. After swinging on the pole, use your jump to catch the wall on the other side. You should not have to use your dashboard to reach these two places, but it's a useful safety net if you need it. Go back to your current location and you should see a dash box. To reach the other side of the wall, you will need to use your dashboard and the cartridge to reach it.

Once there, go up the wall and enter the upper platform. You must grab the yellow and swing even further, and the killer key should be there for you.

The gate of the killers is not far. The door that blocked you at the origin of the key should open up, allowing you to enter the room where you broke the statue. Turn right, behind the block you used to lift the floor to reveal the jump boost, and you can access the killers' door. Good luck to fight him.

There are six keys and Slayer doors in doom: eternal. You need it to unlock a hidden weapon on the doom fortress. You can repeat these meetings when selecting mission, but you will not get any other key at the end. You can not access or acquire killer keys or doors if you play a mission with activated cheating codes.
