Aftermath Detailed Walkthrough

Objectives
1 Meet up with Elias
The Callisto Protocol placeholder quest iconMeet up with Elias
After passing through Checkpoint D521, squeeze through the gap in Access Hall D573's doorframe. Elias will take you to Security D505, where you can get a model for the BI-55 Pistol. Use the Reforge Station to reforge the gun.

If you have not gathered enough Callisto Credits by this point, open the crate by the Reforge and it will have 800 credits. This is also a good time to upgrade the Stun Baton if you have the budget.
2 Get to the SHU
The Callisto Protocol placeholder quest iconGet to the SHU
After reforging the Hand Cannon and/or upgrading the Stun Baton, Elias will tell you that he will guide you on the way to the SHU. Exit through Access Hall D571.
3 Locate the Medical Facility
The Callisto Protocol placeholder quest iconLocate the Medical Facility
Go towards Access Hall D554 and prepare to face the newly turned prison guard. The game will tell you to use your gun, but it is much better to save your bullets and use the Stun Baton.

Take Lift D513 and exit at the dark corridors of Block A2. Here the game will tell you that you can sneak up on enemies and Quick Kill them using the Shiv. Go up the stairs and more enemies will be coming out from the shadows. Head towards Recreation A225, and go left past Administration A215 then climb the vent at the end.
4 Laundry B202
The Callisto Protocol placeholder quest iconOpen Laundry B202.
On the ground next to the sparking robot guard, grab the Implant Bios from the corpse of Sgt. Eric Jane to open the door at the end of the hall. There will be two enemies in the area. You can deal with them in any way you see fit. Once the door is unlocked, go to the end of the hall until you reach a dead end with two doors, one on either side. If you want to get the missable Implant Bios, go down B2 on your right first. If you're in a hurry, take the door to B3 on your left.
5 Maintenance B414
The Callisto Protocol placeholder quest iconKeep on heading to the Medical Facility.
Head towards Maintenance B414. You will hear that there are enemies nearby. Even if you crouch, an enemy will still jumpscare you as you try to crouch your way to the other side. After the enemy is dead, continue down to Access Hall B433 and then straight to Medical Ward C101.
6 Get a GRP
The Callisto Protocol placeholder quest iconGet a GRP.
Once you enter the Medical Ward, you can retrieve the Implant Bios of one Dr. Ewan Hayes. Continue down the hall until you reach Operating C104 across from the Medical C1 sign on the wall. Squeeze through the doors and a short cutscene will play out as you take the GRP from a mangled arm. Get to the other side of the room and another short cutscene will play out including a tutorial on how to use the GRP.

Two enemies will try and ambush you, one skinny regular enemy and one slightly tanky enemy. Once the enemies are taken care of, get the GRP Battery from the table. Be sure to grab the Gate Fuse from the entrance door so you can proceed to Med Office C105. Oh, and more enemies are coming once you take the Gate Fuse, just a heads up.
►GRP Upgrades and How to Get
7 Supply C107
The Callisto Protocol placeholder quest iconTake time for a Supply Run.
Go through Med Lounge C106, get the GRP Battery Pack from the table and the Health Injector from the box by the door, and then head on down to Supply C107. There will be 4 lockers on your right, 3 of which will contain credits and Health Gel, 1 will contain a nasty bugger. Don't open the 2nd locker if you're low on health. Use the Reforge Station to upgrade again or resupply ammo.
8 Maintenance C110
The Callisto Protocol placeholder quest iconLook for an elevator.
Go back towards Med Office C105, and take the door to Med observation C108. Go straight through Access Hall C125, then take a left towards Maintenance C110. Open the door to find a lot of dead bodies hanging. Crawl towards one of the corpse to obtain the Implant Bios of one Ofc. Dachs Symmons. Head down the steps to Maintenance Lift C103. Get on the elevator and Elias will get you down nice and easy.
9 Escape the Basement
The Callisto Protocol placeholder quest iconEscape the Basement.
Once you get off from the elevator, be extra cautious as there are mounds of organic hive matter that will sprout heads and attack you. If you have extra bullets, it is highly recommended that you shoot every mound you see before you enter a new area.

You'll need a Gate Fuse to get out of the basement. Fortunately, this is just on the other side. Unfortunately, there are a lot of enemies on that side including Spitters. Once you deal with the enemies, look for the Gate Fuse on the floor by the gate to Workshop D302 to open the doors. You can also get the Implant Bios of one Ofc. Kerry Brown near the industrial fan and the schematics for the Skunk Gun inside Workshop D302.
►How to Get the Skunk Gun
10 SHU Lift D002
The Callisto Protocol placeholder quest iconReunite with Elias.
Once you've powered up the doors, take the SHU Lift D002 at the end of the hall. Meet up with Elias on SHU Command D701. He'll tell you he can get you across using the gondola. Take the stairs at the other end of the command room, down the ladder and onto the Gondola.
11 Gondola
The Callisto Protocol placeholder quest iconTake the Gondola.
Once you get near enough the SHU, the doors will open and you will get sight of the enemies already waiting for you. You have two options, use your gun or use the GRP and just drop them. The better choice is to use your gun, you will the GRP for when you get inside.
12
The Callisto Protocol placeholder quest iconRestore Power.
Once you're inside the SHU Gearroom D704, the power will be cut off. Get the two Gate Fuses from the panels on the other side of the room, then head on back to the other side. Climb up the boxes and put the Gate Fuses in place of the two control panels on the elevated platform. Once you restore power, the gears will start grinding and enemies will appear.

Save your bullets. Use the GRP to send enemies to the multiple gears and grinders. Once the gears have stopped moving, it's safe to go across and locate the SHU Control Room.
13 Activate SHU Controls
The Callisto Protocol placeholder quest iconLocate the SHU Control Room.
Get the Health Injectors from the Gearroom, before going to through SHU Control D705. Once you open the doors, an enemy will start crawling towards you. Kill it quick and head up the spiral staircase. Activate the console to open up Cell Wing A. This is also a good time for you to use the Reforge Station if you want to upgrade weapons or get more ammo or injectors.
Go back down the stairs and take the elevator down to SHU Cell Wing A, There will be enemies as you get off the elevator, so be prepared to fight.
14 Free the Inmate
The Callisto Protocol placeholder quest iconFree the Inmate.
Surprise, you're freeing the person responsible for crashing your ship, the death of your first mate Max, and the entire reason you're in Black Iron Prison. And they managed to shove you into their holding cell. While you're there, might as well grab Dani Nakamura's Implant Bios.
15 Reunite with Elias
The Callisto Protocol placeholder quest iconReunite with Elias.
After the cutscene is over, continue crawling through the vents to the Waste Management Facility. It's mostly a straight path, lots of crawling under pipes and squeezing between walls until you reach the far end. Go down the ladder, and use the GRP to open up the vent.
16 Get past the droid
The Callisto Protocol placeholder quest iconGet through Security.
Make your way across the Access Hall to the vents on the other side. There are some enemies here, but the real challenge is the security that is patrolling the area. You can try to shoot the robot's head or simply walk in the shadows using the crates as cover. Either option is viable, just get to that vent on the other end of the room.
17 Last Obstacle
The Callisto Protocol placeholder quest iconExit the Station.
Crawl through the vents and when you reach the other side, squeeze through some more pipes and eventually the last obstacle will be the metal death trap that goes back and forth crushing and grinding anything on its path. Once you reach the end, climb up the vent up to the command deck. Resupply with the 3 lockers on the other end of the room before you go down the hatch.

Skunk Gun and List of Upgrades

Aftermath Enemies Encountered

Regular Biophages

Biophage.jpg

Now that you have a gun, these enemies will be much easier to take out from a distance. Keep dodging their attacks and they should pose no real problem unless you get swarmed.

How to Beat Biophages

Spitters

Spitter.jpg
This new enemy type has a ranged attack where it will spit acidic sludge towards you. You can shoot at its head to temporarily prevent it from doing its range attack as you close the distance and finish it off with Melee attacks.

Bloated Biophages

Bloated.jpg

This new enemy type is first seen inside the Medical Facility when you get the GRP. This enemy is much like a regular Biophage with the exception that it can take more punishment and can block more often.

Aftermath Tips and Strategies

Use the GRP to Your Advantage

Hurl enemies at environmental hazards to save bullets. Most stages will have grinders, gears, and industrial fans where you can throw enemies towards.

Deal with Spitters First

Spitter

These enemies will constantly spit acid towards you as you evade melee attackers. Spitters are nots as agile as melee attackers, it is recommended that you try and use cover, and kill the Spitter first as you evade other enemies. Alternatively you can lure them to the big industrial fan!

Shoot the Robot's Head

Use the crates as quick cover to shoot the robot's head. If you managed to upgrade the Hand Cannon, it should take about 2-3 direct hits to the head to terminate the security droid.
