Chapter 6: Environmental Hazard Walkthrough and Wheezer Locations

Environmental Hazard Summary

Entering Hydroponics Walkthrough

	Objectives
1	Go to Tram Maintenance. Follow the Locator back to the Tram, and take the Tram back to the Hangar-Cargo-Tram Control station.
2	Go to Hydroponics. Head down the hall and continue ahead to Hydroponics. You'll go back through the Tram Repair Room from Chapter 1 and through the door on the other end. When you reach the Tram station, override the lockdown to allow transit here by Tram.
3	Create the Enzyme. When you reach the Tram station, override the lockdown to allow transit here by Tram. Continue ahead. In the Hydroponics Central Hub, interact with the Enzyme Control terminal to create the Enzyme.
4	Inject Wheezers. Here's where the chapter really begins. You have to find all 8 Wheezers around the area to complete this task. Go back to the previous room and take the door to the West Tower. In Flow Control, pass through the spraying jets without getting hit. (The first door here has a Ripper Upgrade, so don't miss it) Continue ahead until you reach the West Grow Chamber, where the first four Wheezers are, but be careful as there are plenty of monsters in this large room, and each time you enter and exit a door here, more will appear.

Finding the Wheezers Walkthrough

	Objectives
1	Wheezer #1 In hte West Grow Chamber, the first Wheezer is in the room labeled West Seedling Room B. Inject it and then go back to the West Grow Chamber, and take the elevator up to Floor 3.
2	Wheezer #2 Head to the room labeled Dr. E. Cross and take out the second Wheezer. Go back to the elevator and head to Floor 2.
3	Wheezer #3 In the room labeled West Refrigeration Tower, continue until you reach a zero-gravity area. Fight your way to the top opening doors with Kinesis. At the top, you'll find a Guardian – handle it with the explosive and stasis canisters and then take out the third Wheezer.
4	Wheezer #4 Head back to the bottom, and when you enter the West Grow Chamber, use the Circuit Breaker right by the door and add power to the Doors option on the left. Go directly ahead and the door on the opposite side will now have power. Go inside and take out the Wheezer, but watch out as several Necromorphs will spawn after you do. Then, continue ahead to the East Grow Chamber. After entering the East Grow Chamber, you can get Holt's Rig as explained below.
5	Wheezer #5 Go down the elevator and you'll immediately fight a Brute. Use stasis to get behind it and attack the weak spot on its back, and use the stasis canisters if you're out. Find the room labeled East Seedling Room A and inject the Wheezer.
6	Wheezer #6 Go into East Seedling Room B and grab the Deck Systems Keycard, then leave, because this is Wheezer #8 and you can't reach it yet. Go to the diagonally opposite end of the East Grow Chamber to find a battery. Take it to the wall opposite the entrance to East Seedling Room B and place it in the slot, then use the Deck Systems Keycard. This will activate Zero-Gravity and also spawn several monsters. Fly up to the second floor to reach a Wheezer that was otherwise inaccessible and inject it. If using a keyboard, the button onscreen to use the Deck Systems Keyword will read E, but really you must press Enter!
7	Wheezer #7 This Wheezer will take you far out of your way, but don't worry as you'll naturally be led back to get Wheezer #8 at the end. Go through the door on the second floor to the Air Filtration Tower. In the Zero-Gravity section, use Stasis on the generators to pass through safely, until you reach a room with flames blasting from the walls in sequence. Use your Plasma Cutter to break the locks on each of the doors before you move into range of the flames, then run through before you are hit by the flames. Watch out, as Slashers will suddenly spawn just as you are about to reach the next room. Once you make it through, you'll finally find Wheezer #7.
8	Wheezer #8 Continue ahead and you'll reach Wheezer #8 as a matter of course.

Fighting the Leviathan Walkthrough

	Objectives
1	Kill the Leviathan. 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.
2	Phase 1 In the first phase, shoot the yellow bulge in each of the Leviathan's tentacles when they emerge, using explosive canisters as much as possible to save ammo.
3	Phase 2 In the second phase, use Kinesis to grab the projectiles it shoots and fling them back at it. Fling the first orb against the second to break it, then throw the third back into its mouth to damage it, until the phase ends. If it goes well, you shouldn't even have to move.
4	Phase 3 In the third phase, you'll need to deal enough damage to it to knock it out before you run out of air. There's an Oxygen Tank in the room you can grab if you're having trouble. It will use both its attacks in tandem, so get some choice hits at its tentacles when they emerge, then be ready to handle the orb projectiles with Kinesis. Get in a good rhythm and the Leviathan will be flung out into space, ending the chapter.

Chapter 6: Environmental Hazard Tips and Strategies

Get Holt's Rig

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

Use Explosives on the Guardian's Stomach

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.

How to Beat Guardians

Aim For the Leviathan's Tentacles

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.

Use Explosives and the Pulse Rifle on the Leviathan

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.
