The Criticality mission is an action‑packed part of the Destiny 2 DLC where you’ll be racing against time, collecting coolants, and taking down disruptors to keep the Reactor stable. Along the way, you’ll use special abilities like Matterspark, Mattermorph, and the Relocator to reach hidden areas and complete objectives. This guide will walk you through every step in an easy way, so you know what to do.
Criticality Mission Walkthrough in Destiny 2 DLC
As you fight through the mission, enemies you defeat will drop coolants that keep your timer going. After grabbing one, head back to the Reactor and move on to each generator area.
Your goal is to destroy three disruptors in each section.
- The first disruptor is right in the open.
- The second one can only be reached after breaking some Vex boxes.
- The third one is hidden behind a vent, so you’ll need to use your Matterspark ability to slip through and reach it. Once those are down, access the terminal and break open the Vex box there to move forward.
Second Coolant Location
As you push toward the second coolant, you’ll start using both Matterspark and Mattermorph. You need to destroy the three disruptors to open the terminal:
- Two of them work exactly like before.
- The third one is a little different; this time, you have to use Matterspark to smash a pylon instead of crawling through a vent.
Third Coolant Location
To reach the third coolant, you’ll rely on Mattermorph to get into places you normally couldn’t. Keep breaking the disruptors, one of them is tucked away in a spot you can only reach by using the Relocator device. Once you’ve handled all of them, head back to the Reactor.
Final Fight at the Reactor
Back at the Reactor, a Hydra will show up as your final challenge. When you bring its health down to about 50%, it will throw up a shield. To bring that shield down, kill Vex in the area until the three disruptors appear and destroy them. After that, you can finish off the Hydra. Defeating it stabilises the Reactor, and you’ll earn your rewards. After the Hydra is down, return to the Altar to deposit the final Capsule. Speak with Lodi and Orin to move the story forward.
