| 1 | Now that the Wheezers are finally done for, we're almost out of Chapter 6, but there's one big obstacle in our way. Back in the Hydroponics Central Hub, continue toward Food Storage and activate the Airlock Control. The next room is the boss room; grab all the goodies floating around you can before you enter the room, because once you disembark, the battle begins. |

On first entering the East Grow Chamber via the West Grow Chamber (after Wheezer #4 in the steps above), turn left to find a yellow bulge you can shoot. After it deflates, another will appear more nearby, so shoot it as well. This will open up a path to the Holt's Rig collectible.
Holt's Rig is one of the collectibles needed to unlock Master Override, making new doors around the map accessible, as part of the You Are Not Authorized side mission.
List of Side Missions and How to Unlock
When you fight the Guardian, maintain your distance and use the explosive canister carefully, as hitting its vulnerable stomach can kill a Guardian in one hit. It won't be effective unless the Guardian has its stomach clearly exposed, so take your time to get in a clear strike.
Much like the Tentacle which appeared in earlier chapters, the Leviathan's tentacles has the same weakness, a bulging yellow tissue that connects it to the main body.
There will be some explosive cannisters in the Zero Gravity area. Use them to conserve ammo. It is highly recommended that you have the Pulse Rifle equipped due to its singular concentrated rounds and high magazine capacity.
