In this page you can find a walkthrough for Reboot mission found in Prey. This is one of the main story missions and you get it right after you enter the Power Plant. You must reboot the titular reactor which removes the blockade issued by Alex Yu. After doing that you can use airlocks and the main elevator again. The journey to the reactor is rather long and, when you get there, you must do a number of actions that will allow you to reboot it.
- Reach the entrance to the Power Plant
- Defeat the Technopath that blocks the entrance to the Power Plant
- Reach the Reactor Control Room
- Get into the Reactor Control Room
- Reboot Talos Power Plant
Reach the entrance to the Power Plant
This missions starts shortly after entering the location called Life Support. Mikhaila Ilyushin contacts the main character and gives you guidelines on how to remove Alex's blockade.
The first step of Mikhaila's plan is to reach the passage to the Power Plant located on level -2. Start on level 1 and go to a Grav Shaft. You can find it located south-east from the starting location but between this place and your target destination there is an area guarded by Etheric Phantom and corrupted operators. You can defeat them or avoid the enemies and run to the Grav Shaft. When you reach level -2 you must go west and when you find the fork in the road you must turn right. Your attempt at entering the Power Plant will result in failure. Activate the Psychoscope and scan the passage. You learn that it is blocked by a Typhon Technopath.
Defeat the Technopath that blocks the entrance to the Power Plant
The Typhon Technopath is in the Water Treatment Facility that can be accessed by using the left turn in the fork that you came across a few minutes earlier. The fight with this monster starts right after you forcefully open the door that leads to the Water Treatment Facility. The best way to start this battle is to throw a Recycler Charger first. Then, you can use psychic abilities or, e.g. the shotgun to weaken the creature. You can face him in the facility or in the corridor that leads to it but remember that when you use the second option it is harder to avoid his electric attacks.
After killing the monster you can go back to the entrance to the Power Plant and use it.
Reach the Reactor Control Room
When you enter the Power Plant you receive new objectives for this mission but also you unlock a new side mission called Assist Mikhaila Ilyushin. Warning - You should meet with Mikhaila after your visit in the Reactor room because, by doing that, you won't have to worry about the time limit in this side quest.
You must reach a new Grav Shaft - it is located east from the starting point. On your way there you can come across a Security Station and it is a good idea to visit it and download the Power Plant's map (you need Hacking II ability). But before you get the map you must defeat Cystoids inside of the station (you can shoot them through a small window in the station so you don't have to risk a direct confrontation).
The Grav Shaft takes you to level -1 where you appear near the Coolant Chamber. There are many Phantoms and Mimics in this location so you should defeat them first if you want to explore this part of the Power Plant without any problems. You should attack the monsters one after another, allowing them to reach the higher balconies where you started your exploration.
After defeating the Typhons go to level -2. The big passage on the west leads to your target destination but it is closed which means that you need a keycard. Examine the area south from the passage and go near the place with flames presented in the picture. Extinguish the flames by using the GLOO Cannon (if you don't have it you can find one nearby) and examine newly found Talia Brooks' corpse. By doing that you get the Coolant Chamber Keycard. Use it to unlock the new passage.
Go west. If you want to start doing Assist Mikhaila Ilyushin side quest then you must head to the office in the north but you should return here after you complete the main mission described here. You must go to a new Grav Shaft that is guarded by Greater Mimics (you can use the wrench to get rid of glue balls). Use the Grav Shaft to reach level -3.
Enter the room with the Reactor and head north. There, you can find a stairwell that allows you to go to the lowest level, -5. Your destination is the Reactor Control Room located in the west part of the room. Sadly, it is closed and you must find a way to get in.
Get into the Reactor Control Room
There are two ways of accessing the Reactor Control Room. The first method is to find a Reactor Access Keycard that opens the door to the control room. The keycard can be found in two places - by examining Nicholas Stillwater's corpse on one of the higher balconies in the west (the body is in the lower part of the southern Grav Shaft -picture 1) and by examining Guy Croal's corpse in the balconies right above the reactor (picture 2).
The second method is to access the control room by going through a hole in its roof. Start by getting on the balcony right above the control room (the picture above). Jump over a balustrade and land on the roof. Sadly, you must use Leverage II to move the heavy metal object that covers the hole.
Reboot Talos Power Plant
First, you should read the Reactor Emergency Procedures that has a hint on how start the rebooting procedure. Approach the central console and select the first option to unlock the safety buttons. Interact with them by following a pattern, you can see it in the picture above - the correct order is: Magnetosphere (1), Substation Power Grid (2), Photovoltaic Rings (3), Gravity (4), Life Support (5), Main Reactor (6).
After receiving a confirmation that the combination is correct you can start the reboot. It will be interrupted by detecting a malfunction connected with damaged reactor diverter.
Head to the Reactor. You don't have to enter the room right away because there are Cystoids' nests near the entrance. The best way to get rid of them is to use psychic powers or firearms. In addition to that you can get radiation sickness but inside of the control room you can find, e.g. Anti-Rad.
Find the diverter, presented in the picture (you can also listen to the TranScribe lying near you) and interact with it. This problem can be solved in two ways. First method is to use Repair human ability to fix the diverter.
The second method is to find a new diverter. This item can be found in the Secure Storage Room. The room is closed and to open it you must use Hacking III ability. The unused divider is on one of the shelves (the picture above) and you must move it to the reactor room.
Warning - In the northern Secure Storage Room you can also find, e.g. a few unused turrets. A good idea is to place them in the area (if you are using alien abilities then you must hack them first) because when you complete this mission a new powerful monsters will appear in the reactor room.
You can now return to the Reactor Control Room and issue the command to complete the rebooting procedure. This time everything goes well which marks the end of this quest. Listen to what Mikhaila and Alex have to say. You learn that the blockade is now removed and you can freely explore Talos I station again. You can now go back to The Keys to the Kingdom main mission, started much earlier.
