This achievement takes place in the Hawaii map. Start by teleporting to La Luna
@teleport La Luna

Activate the altar shown in the screenshot (crosshair is right on it)


Now onto the secret caves:
@teleport Junkyard
@give 519 (RPG)
@give 520/5 (5xRPG Ammo)

Shoot the wall a few times to uncover the secret passage


Activate your NVG since it'll be very dark and here take the left side.


In here, place a bedroll because you may die by hitting the lava (remember to claim the bed)
When reaching the center platform go to your front.


Then, on this crossroad go to the left.


After climbing down you should see a small entrance, the second altar is inside. Activate it and go back.


Fall back to the room with the center platform where you've placed the first bedroll, now going into your right side.
This jump might be tricky so use another bedrooll and claim it.


After arriving on the right side, hug the left wall and keep going until you find the third and final altar, which will teleport you to the boss room. (Sadly I can't activate it again, so no more screenshots!).


It's good to use another bedroll here before the fight, since you may die quickly. The boss himself is easy, a single drum from Hell's Fury should be enough! When he finally dies, interact with the altar on the boss room to complete the achievement!
