Chapter 4: Obliteration Imminent Detailed Walkthrough

	Objectives
1	Meet Hammond in the Captain's Nest. After arriving at the Bridge Tram Station, head towards the Main Atrium. Take a right from Bridge Hall Storage, this room requires Level 2 Clearance, which you will get once you meet up with Hammond in the Captain's Nest. Take a left from the Store to get to the Main Atrium. Head down to the front of the Bridge and down the elevator to the Captain's Nest. Interact with Bridge Security to begin a Side Mission. ►You Are Not Authorized Side Mission Guide
2	Activate the Elevators. Get back up on the Bridge and head towards the Security Room to activate the elevators. Get ready to be attacked by a Brute! As soon as you see the doors of the Security Room deforming, back away and get some good distance between you and the coming Necromorph. Use Stasis to temporarily stun the Brute giving you time to get to its back and shoot its weakspots.
3	Reroute Power from Mining Administration. Take the elevator facing the Security Room and go to Floor 2. Go through Administration Access Corridor to Mining Administration. Go through the door and kill the Slashers that are going back and forth inside the room. Go into the Main Fuses Room to your left and destroy the plasma cell by the door. Take caution as you reach the far side of the room avoiding the electrical surges from the floor towards the power terminal. Reroute the power and return to the elevator.
4	Reroute Power from Electrical Systems. Go to Floor 3. Head into the Comm Array and make your way to the end of the hall to Electrical Systems. Go through the maze, avoiding electrical surges from the floor. You can also lure Necromorphs towards those floor tiles to save on ammo. As you reach the end of the room, a Brute will come charging at you. Use Stasis to slow it down and gain the opportunity of shoot it from the back. Recharge your Stasis and use it on the two live wires, then proceed to the reroute terminal. Return to the elevator.
5	Reroute Power from Water Purification. Return to the Atrium, some Necromorphs will spawn as you get off the elevator. Once they are dealt with, go to the elevator on the other side of the shaft, and go up to Floor 4. Follow the hall until you are met by necromorphs. After dealing with them the reroute terminal will be in the hall just before Exterior Access.
6	Calibrate Three ADS Cannons. Go through Exterior Access and keep on following the hall to the elevator and past that until you reach the Airlock blast door. Take-off and fly towards the first ADS Cannon on your left. There will be O2 Recharge stations just across every cannon. All that's left is to destroy a few asteroids to calibrate the ADS cannons. Return to the Captain's Nest afterwards.

Chapter 4: Obliteration Imminent Tips and Strategies

How to Calibrate the ADS Cannons

When you're near enough to interact with the cannon, all you need to do is to guide the aim of the cannon and fire a few decent hits to the asteroids. After a few sure hits, the gauge will reach 100% and the cannon will be calibrated.

Shoot the Brute's Back

The Brute will have yellow tissue that connects its arms to the rest of its torso. Once you dismember its arms, it wiill go down and you can killl it. Alternatively, its backside is exposed with this critical yellow tissue. Shooting it in the back is also an option.

Do Not Shoot Pregnant's Stomach

Pregnants are a type of Necromorph with enlarged stomachs that hold Swarmers, hence the name. If you shoot its body, the stomach will burst releasing a bunch of Swarmers that will add to your list of current Necromorphs to deal with. Instead, shoot at its limbs to kill it.

Be Mindful of Electrical Surges

Signs of an electrical surge will be seen as pulsing energy emanating from the floor. Avoid these at all times as getting caught in its field will result in damage. Alternatively, it is a good tactic to get Necromorphs into these fields.
