Destiny 2: Scourge of the Past raid guide: Vault Access and unlocking Insurrection Prime

Unlock the boss now so you can fight and kill the boss later

Ryan Gilliam (he/him) has worked at Polygon for nearly seven years. He primarily spends his time writing guides for massively popular games like Diablo 4 & Destiny 2.

After escaping the Servitor of doom and climbing up the pipes, you’ll find yourself in the final boss arena of Destiny 2: Black Armory’s Scourge of the Past raid. But before you can take down Insurrection Prime, the giant Metal Gear, you’ll have to free it from its prison.

In this guide, we’ll teach you how to summon tanks quickly and blow open the boss.

Starting the fight

First, you’ll need to split your crew up into two crews: Outside and Inside. The outside crew is mostly going to focus on enemy clearing while the inside crew will need to jump in tanks and grab powerful buffs.

Once you’ve divided the crew in half, track down the giant Servitor and kill it. This will lower the electric fences blocking the arena’s underside and start the fight.

We’re going to break this next section up into roles to make it clearer.

Summoning the tanks


Outside players should have burst supers like Blade Barrage or roaming supers like Titan hammers or Dawnblade. Tether can be great here when using Orpheus Rigs. You’ll also want to make sure the team has a wide variety of damage element types at their disposal. Weapons like Borealis or Hard Light are actually pretty potent here since they can switch between Arc, Solar and Void easily.

While you allies go underground, you’ll need to keep them safe and listen for their calls. Large groups of Shanks — with powerful elemental shields — will spawn around the arena and start to make their way underground. If you don’t kill these, they’ll cause hell for your teammates below. Use the appropriate element to pop their shields while they’re still bunched together — the ensuing explosion will likely pop all the Shanks around them as well.

Other than Shank clearing, you’ll need to kill the big Servitor on the regular. Wait for your allies to call that all three of them have collected a buff and that they’re ready for a refresh. Kill the Servitor to refresh their buffs. When they’ve all collected a second buff, they’ll call for a Servitor kill again. Oblige them to lower the electric gates and let them back up.

And that’s it for the Outside folks, although you’ll want to keep an especially close eye on the rooftops for Vandal snipers for your own safety.


Once you’ve taken the first big Servitor down, all three Inside folks should pick a different hole to run into. After entering your hole, take a right and locate a generator. Approaching it will show you a hologram of either a triangle, square or circle. However, one of these buffs will be red and cycle between all three — this is corrupted and interacting with it will cause everyone to die.

Have each player melee a generator to grab one of the buffs. Call out the symbol you punch so your allies know what’s still on the table — if you get the corrupted one, keep running around until you claim a different symbol. Be sure not to melee your buff until all Inside players are below ground as this will start the lightning fence back up and lock them outside.

Once you have a buff, stay away from other buff holders, as getting too close to them will tether you together and start dealing damage. If you need to pass in the tunnels, do it quickly to avoid taking too much damage.

When all three players have the buff, tell the Outside team to kill the first Servitor. When the first Servitor is dead, your buffs will be refreshed. Run around until you find the same buff you hit last time. Melee it to collect another stack.

When all players have their buff x2, tell the Outside team to destroy the second Servitor. When the gates go down, exit into the outside area and move toward a generator. (To make it easy, we had square go left, triangle go right and circle go top where the Servitor first spawns.) Wait for your allies and drop the buff into the generator at the same time. Depositing two buffs at once will spawn a tank for all three Inside players. Jump in and get ready to deal damage.

Dealing damage

Outside players don’t have a lot to do here other than dodge the missiles. Inside players will need to shoot the mass in the center of the arena with tank shells — don’t forget to use your missiles as well since they do a lot of damage.

However, rockets will be dropping from the sky in an attempt to destroy the tanks. Have each player set up at the end of a different road so they can all see the middle without getting in each other’s way. Rock back in forth in the tank as the missiles drop from the sky. This should keep you relatively safe inside your tank. Blast away with missiles and rockets until the counter on the left of your screen hits zero. If all three players do this correctly, you should be able to lower three-fourths of the boss’ health in a single go.

If something goes wrong and you don’t make it to at least the first tick of the boss’ health, Insurrection Prime will kill everyone and start you over at the beginning. The same will happen if you take too long summoning the tanks.

Once the tanks explode, jump out and repeat the fight. When you’ve destroyed all four arms holding down the boss, the fight will end and a chest will spawn at the back of the arena.

Congratulations, you’ve earned the right to start battling the true final boss: Insurrection Prime!
