Take the oxygen kit offered by Zane, melee the door, and head outside to find oxygen kits for your companions. The first oxygen kit is toward the south, by the DAHL ship. The second oxygen kit is located to the west, on the platform that juts out past the cliff

Throw Explosives into the Thruster

Hand over the oxygen kits to Zane and Amara and begin moving southeast to Elpis’ core. When you reach the area with the large thruster, kill all Order and Ripper enemies. After clearing the area, pick up explosives from the marked canister and throw them into the thruster three times.

Activate the Engine

Activate the engine by interacting with the terminal behind it. Make your way through the open gate and jump across the floating platforms to pass through a cave. On the other side, use the jump pad next to an active thruster to cross the chasm and grapple up to the next area. Jump across the broken platforms and use the grappling hook again once you reach the end.

Take the Elevator to the Surface

Jump and glide over the platforms ahead to fight through the enemies and reach the DAHL elevator. When the elevator doesn’t work, interact with the terminal in front of the power source. Then, use your grappling hook three times on each of the three turbines to spin them. When you interact with the terminal again, enemies will appear.

Use the elevator and employ your grappling hook to climb higher when it stops. Ascend using the climbable walls and ladders to reach a control room where the Ripper Queen appears on the other side of the window.

Reach Elpis Core

Head outside through the door on the left to assist Zane and Amara by killing all the Rippers attacking them. Once all the enemies are dead, follow Amara and enter the portal she creates. Within the Phase dimension, continue heading straight until you trigger a cutscene with Lilith. Following the cutscene, your second boss fight with Callis the Ripper Queen begins.

Moon-Maddened Callis has a few new attacks to throw at you since the last time you faced her in Her Flaming Vision. When she is below half health, Callis will create a red holographic web above you and become invulnerable. Avoid the holograms on the ground that slow you down while killing the spawning Ripper enemies as quickly as possible. Once you’ve killed all her minions, Callis’ web will be destroyed.  

During the battle, chunks of debris will fall onto the arena, creating shockwaves that you must jump over. A part of the platform where the debris lands will turn red and disintegrate within a few seconds. Avoid these sections of the arena when they begin to glow red.
