Aftermath

**Aftermath** is the third chapter for *The Callisto Protocol*.

## Walkthrough

### "Access Hall"

Make your way to the end of the hallway to a set of stairs to the Access Hall. You will come across a Security Bot, but it won't attack you. After that, Jacob will meet up with Elias. Follow him for the time being and don't forget to grab the loot in some lockers to your right. In the next room, Elias will grab a gun handle for Jacob. You will be introduced to the REFORGE Station, a shop to where Jacob can buy and sell various items throughout the game. Look in the chest on your right for 800 credits, then interact with the station and print your first firearm weapon, the Hand Cannon. You can also purchase any ammo and Health Injectors if you need them. Once you get to the next hallway, be ready for a security guard version of the Grunt to attack you. It does take longer to kill these versions of the enemy type. After you kill the Grunt, head for the elevator on the left to descend to the lower level. Here, you will be introduced to the sneak kill mechanic. Simply crouch and sneak up behind to kill the Grunt standing in the hallway.

### "Big Mouth Introduction"

Once you head up the stairs, you will be introduced to a new enemy type called the Big Mouth. Be ready to avoid its long range spit attack and try to close the gap or destroy its head to prevent it from spitting, forcing the Big Mouth to resort to melee. After you kill the Big Mouth, head left towards the vent into the next room. There will be two Grunts ahead of you, so using stealth is the recommended course of action to avoid alerting them and saving ammo. Once you kill the Grunts, go back to the opposite end of the hallway to use the shiv on the dead guard to extract the CORE Device from his neck for the key to unlock the door to the Laundry Room.

### "Medical Rooms"

Once you enter the room, a Grunt will emerge from the grate ahead of you and attack you. After the Grunt is killed, go to the right up ahead to collect the loot and extract the CORE Device from the dead body. When you enter the Medical Ward C101, a cutscene will play showing Jacob picking up a dead security guard's severed forearm and he retrieves a new tool called the GRP. When you retrieve it, go down the end of the room and collect the Gate Fuse to unlock the door on the opposite end. As you start making your way there, a Grunt will appear and attack you. Be cautious of the Big Boy variant that emerges from the grate. The best strategy is to throw the regular Grunt away from you using the GRP to separate them or simply throw him into a wall for some simple damage to him while focusing on the Big Boy first. The Big Boy variant of the Grunt takes more damage than the usual Grunt's do. Once you kill the Grunts, break the glass on the cabinet to obtain the loot that is stored on the shelves and proceed to install the Gate Fuse to unlock the door. When you go through the door, turn left and grab the Health Injector if you need it. After that, go right and you will enter a room with a REFORGE Station and some lockers to loot. Be careful opening the second locker because it contains a Parasite. Head back to the Med Observation C108 door to continue down the path and you will enter a room with hanging bodies and dismembered guards. While you make your way toward a set of stairs, make sure to grab the CORE Device from the dead body on the floor before proceeding. When Jacob enters the elevator, it will start to descend too fast and you must slow it down. Once it is done, Elias will tell Jacob that the power must be reset on the elevator.

### "Blood Worm Encounter"

As soon as you walk off the elevator, you will be attacked by a new enemy type called the Blood Worm. The only way to kill this enemy is to complete the QTE in order to free Jacob. When you kill the Blood Worm, take care of the Grunt that is in the room. Continue along by jumping down the platform until another Blood Worm attacks. Once you kill it, keep proceeding down the path until you reach Basement 04 Storage. Here you will find another Blood Worm pod up ahead of you in front of the fan. Try and shoot it from a good angle to kill the Blood Worm. If you can't, just do complete the QTE like before. After killing the Blood Worm, deal with the Grunt that emerges from the grate. Down forget to loot the chest that is behind where the fan is in the room. Before collecting it however, you will be ambushed by another Grunt. Also, there will be a dead guard with a CORE Device that can be extracted. Up ahead, there will be several enemies to kill. A couple of Grunts and a Big Mouth. For quick kills, use the GRP to throw the Big Mouth into a spike wall saving ammo to focus on the Grunts after that. When the Biophages are dead, search the room for a Gate Fuse to power up the door in order to progress to a lift at the end of the hall.

### "Special Housing Unit"

Upon exiting the lift, you will officially enter a new area called the Special Housing Unit. A place where the most dangerous inmates are incarcerated. Go to the left and open up the door, as Elias and Jacob will meet up again. He will then tell Jacob to use the gondola that is below them. While waiting for the gondola to arrive, take the opportunity to use the REFORGE Station to purchase upgrades, ammo, Health Injectors or to sell any excess items that you have. Once on the gondola, the doors will open and two Big Mouths and a Grunt will attack you. The smart idea is to throw one of the Big Mouths off the platform to make things easier and save ammo. After you kill the enemies, the power to the room must be restored. Head to end of the room and grab the two Gate Fuses that are next to the locked door. There is also a Health Injector on your left if you need it. Head to the upper level and grab the CORE Device that is on the dead body. Insert the Gate Fuses into the boxes and a set of giant spinning gears will activate. Several Grunts and Big Mouths will attack afterwards. Stay alert, and try to throw as many enemies into the gears with the GRP for quick and easy kills. Do not forget to loot the enemies in between the waves. The first wave will consist of two Grunts appearing on the upper level. The second wave will be a Big Mouth and Big Boy variant of the Grunt. More regular Grunts and the security guard variants will also attack you. When all the Biophages are dead, you can then loot all the dead bodies in the room. You will be able to unlock the SHU Control D705 door and progress to the next room. Upon opening the door, a severed Big Boy will crawl towards you, so stomp kill it or use your Hand Cannon to kill it. After that, move toward the stairs that are ahead to the upper floor. You will come across another REFORGE Station on the opposite end of the room, Use it if you need to sell or make any purchases before activating the console by the window. There is also loot to pick up which includes an Energy Converter. Head back down the stairs into the only unentered door and you enter the lift down to the cells. A group of enemies will attack Jacob that consists of a regular Grunt, a security guard variant and a Big Mouth. Eliminate the Big Mouth first, to make it easier to kill the two Grunts. After those enemies are dealt with, interact with the switch that is next to the cell. A cutscene will play in which, Jacob will enter the empty cell, only to be locked in by the Outer Way rebel he encountered in the prologue, Dani Nakamura. Elias then shows up and tries to convince Dani to work with them, but to no avail. Then, an emergency lockdown engages and Jacob is stuck inside of the cell. Once you regain control of Jacob, you must climb out to the top of the cell. Make sure to grab the audio log on the table before leaving. With that collected, use the shiv on the control box to open the door and Jacob will automatically climb up to the top and enter the air vent. Be careful of the Grunt that runs towards you on upon exiting the vent.
