The Devils' Lair (strike)

"The Fallen will continue to claw at the walls of our city unless we strike them down. Beneath the ruins of the Cosmodrome, in the shadow of an old colony ship, we've located the House of Devils' lair, and the High Servitor, feeding them their strength. We must destroy this machine god, and send their souls screaming back to Hell."

- Commander Zavala, mission briefing

The Devils' Lair is a Level 8 Strike that sends Guardians deep into the lair of the Fallen House of Devils to eliminate Sepiks Prime.

As the Prime Servitor of the House of Devils, Sepiks Prime is guarded by some of the Devils' best troops. Guardians on The Devil's Lair strike mission must fight all the way inside the lair and defeat Sepiks in order to smash the House of Devils' morale, and weaken their attacks against the Last City.

In the Rise of Iron expansion, the Strike was revamped with new Splicer enemies and the boss being Sepiks Perfected.

 * COMMANDER ZAVALA: The Fallen will continue to claw at the walls of our City unless we strike them down. Beneath the ruins of the Cosmodrome, in the shadow of an old colony ship, we've located the House of Devils' Lair and the High Servitor feeding them their strength. We must destroy this machine god and send their souls screaming back to Hell.

{Gameplay}

The fireteam enters the complex.


 * GHOST: Fallen and Hive. Let's hope we can avoid the crossfire.

The fireteam clears out the refinery and deploys a Ghost to hack the Fallen Shield Mesh Generator.


 * GHOST: Pretty complex. I'll need time.

The fireteam defeats the first wave of enemies.


 * GHOST: The Fallen are getting smarter. It's like the entire system is wired to a...

An alarm sounds.


 * GHOST: I'll work faster.

The fireteam defeats the second wave of enemies.


 * GHOST: I'm close. But, just so you know, there's more Fallen and Hive on the way.

The fireteam defeats Naksis, Devil Baron during the third wave of enemies.


 * GHOST: Barrier is down. We can move now.

The fireteam moves through the next area and into a clearing.


 * GHOST: The Lair is up ahead, under that Colony Ship. Just on the other side of all those Devils.

A Devil Walker is deployed in front of the fireteam. The fireteam destroys the Devil Walker and continues into the Devils' Lair.


 * GHOST: So, this is the Devils' Lair...

After entering Devils' Lair, the fireteam encounters and destroys Sepiks Prime.


 * ZAVALA: Sepiks Prime cast a great shadow over our City. With its destruction, the Fallen Devils will grow weaker. But we must stay vigilant. The Fallen are crafty. They'll find ways to survive. They always do.

 * SHIRO-4: The House of Devils marked you as public enemy number one after you trashed their Prime Servitor, but your old friend Sepiks Prime is back, and better than ever thanks to the Devil Splicers and SIVA. Zavala's not too happy about the idea of the Splicers playing god-maker, and I can't blame him.


 * GHOST: So what you're saying is it's time we return to the scene of the crime! I'm sure the Fallen will be happy to see us.

{Gameplay}


 * SHIRO: The new and improved Sepiks is holed up in the Devils' Lair. You know what to do.

The fireteam heads inside the building.

The fireteam reaches the Refinery. A large portion of the wall in the hallway has been cut out.
 * GHOST: Hmm. The Hive are still holding ground in the Refinery, but I'm also tracking multiple SIVA energy signatures.


 * GHOST: Well, that's new.

Either the hole is open and the hallway gate is locked, or the hole is blocked by a laser grid and the hallway gate is open. The fireteam continues deeper into the refinery and eliminates all Fallen and Hive in the area.


 * GHOST: The Splicers have a laser grid blocking the way. I should be able to disable it. In the meantime, do not touch the lasers, and watch my back.

Either Fallen or Hive enemies will attack the fireteam. If the enemies are Fallen, then after killing off the first wave:

If the enemies are Hive, then after killing off the first wave:
 * GHOST: Halfway through, but we've got major Hive reinforcements inbound! Good luck!


 * GHOST: The Splicers really know how to encrypt their systems! But I got this. Halfway through.

The fireteam defends against another wave of enemy reinforcements.


 * GHOST: Got it! Grid's clear. Let's get out of here.

The fireteam moves through the opening and continues to The Blast. If Hive are present:


 * SHIRO: Guardian, I've got reports of Hive activity near the Devils' Lair. You seeing anything?

GHOST: Uh, yeah. We've definitely got Hive. And apparently they hold a grudge because they're mad. And I think they're letting the Fallen know it.

If Fallen are present:


 * GHOST: Déjà vu. Me, you, a sea of Devils, and an angry machine-god waiting on the other side. I'd say "lock and load," but I'm sure you already did.

The fireteam kills all enemies in the area and continues into the building.


 * GHOST: Why would the Splicers rebuild Sepiks? They already have SIVA.


 * SHIRO: I can make a guess. Maybe an offer to the other Devils? A show of power? You know, "in SIVA we trust" and "in SIVA, all things are possible"? Get in there and show them that their "god" is nothing but metal and tech.

The fireteam enters the Devils' Lair. Sepiks Perfected is protected by a shield and surrounded by Dregs.


 * GHOST: Sepiks Perfected, in all his glory.

The fireteam eliminates the Dregs, and Sepiks' shield disappears. The fireteam engages Sepiks. After weakening Sepiks a little, it gains an elemental shield. A Captain appears with a matching cannon, and the fireteam kills the Captain, takes its cannon, and fires it at Sepiks to take down his shield. The fireteam repeats this twice more as Sepiks changes to a different elemental shield. Once all three elemental shields have been destroyed, Sepiks becomes permanently vulnerable.


 * SHIRO: Nowhere for Sepiks to run this time!

The fireteam destroy Sepiks Perfected.


 * SHIRO: Sepiks was the Splicers' next big play: present a god for all to worship, then control the flow of ether to control the House.


 * GHOST: I guess they didn't factor us into the plan.


 * SHIRO: Any wrench we can throw in their works is a good thing. And Guardian, you make one hell of a wrench.

Trivia

 * The Devils' Lair was one of the few Strikes that was not revamped with the The Taken King expansion. With the release of Rise of Iron, the Strike was revamped into a brand new Strike accessible at the Light level 320 version and above.
 * In Destiny 2, if The Devils’ Lair is in the Nightfall rotation, more specifically when doing the Grandmaster difficulty, the redux version of the Sepiks theme Prime will play instead of the original theme during the final boss fight.
