In this page you can find walkthroughs of additional mission in Prey that are associated with two most important potential allies of the protagonist - Dayo Igwe and Mikhaila Ilyushin. You can help both of those characters and the missions associated with them are time-limited. Once you've supported them, an opportunity to complete additional tasks commissioned by them might arise.
This mission must be completed if you want to "recruit" Dayo Igwe. This mission can be failed. Once that happens, you won't receive any help from him, nor any additional tasks in the latter part of the game.
You can get this mission automatically after getting to Talos I Exterior and completing Restore from Backup main mission in the Deep Storage. During the fly Dr. Igwe contacts with you and asks for your help to get him out of a container drifting in the space.
You have 7 minutes to rescue Doctor Igwe (otherwise he will die), and even if you won't be in a hurry you still only need a half of that time. Fly to the Igwe's container marked by the game. When you get closer to it you must read its number - 2312.
Warning - If you want to kill Igwe you must interact with the panel on the container's side and complete a hacking mini-game (Hacking ability required). Since Igwe has no suit he dies immediately after opening the container. Because of the obvious reasons this action fails the mission. A "positive" information is that by examining Igwe's corpse you can get a TranScribe and 2 neuromods.
Now, you must fly to the terminal that controls the docks (you can also skip the previous step because Igwe's container number is not generated randomly but is always the same). Watch out for the Cystoids in the area, you should get rid of them first. When you activate the terminal you must enter the number 2312 and then select the option to dock a container. By doing that you save Igwe and get the access to the Cargo Bay.
This mission can be officially completed after you get into the Cargo Bay. Find the Grav Sahft that allows you to get on the level 2. When you are on the upper level you must search for Dr. Igwe and speak with him. As your reward for saving his life you get 2 neuromods and Psi Hypo Fabrication Plan. Igwe himself will soon head to Yu's office in Talos I Lobby - you won't have to accompany him during the journey.
This is a second mission connected to Dayo Igwe. You will receive it only if you've managed to save Igwe during Doctor Igwe side mission.
After some time has passed since rescuing Doctor Dayo Igwe, the man should contact you through the radio and this conversation will unlock the described mission. The conversation will be about retrieving the connectome of the pianist Gustav Leitner. An audio recording (Leitner Music Sample) will be used to complete the task.
Head to Crew Quarters and then to Crew Cabins A on level 1. Doctor Igwe's cabin, numbered 104, is your destination. Once inside the cabin, open the audio logs tab and play the recording you've just received from Igwe (screenshot 1). This will reveal a safe shown in the second screenshot, hidden behind the pianist's poster. Collect the connectome (as well as other valuable items) from the safe.
Afterwards, head to Yu's office located on level 3 of Talos I Lobby. Initiate a conversation with Igwe to give the man the connectome you've just acquired. Aside from the man's gratitude and random items, you will also receive A Gift to the World achievement / trophy.
Assist Mikhaila Ilyushin
This mission should automatically be unlocked after your first visit in the Talos Power Plant. You will receive a message from Mikhaila asking you for assistance. The woman can be found in Cooling Monitoring Room located in the western part of level -2.
Note - it's advised to take on this mission after you've restarted the Talos I reactor during the Reboot main mission. This is because after meeting with Mikhaila the time limit will initiate. You will have 2 hours to complete the task and even though it might seem like a lot, you will spend a lot of time exploring the reactor (you won't be able to use the floodgate until the reactor is rebooted). You should speak with Mikhaila for the first time once you're on the way back from the reactor, heading towards the Life Support section of the station.
The mission is about finding injections (booster shots) required to fight the symptoms of Mikhaila's rare disease. The delay in the previous paragraph was suggested because you need to go to Talos I Exterior. The floodgate is located nearby and it will be unlocked once you've restarted the reactor. Once outside, go through the outer space to reach the marked location. You must be careful, as there are Cystoid nests and a Telepath located near Mikhaila's destroyed office - eliminating the later should be a priority. Once you've dealt with the enemies, enter the destroyed room. Mikhaila's Booster Shots can be found in the cabinet shown in the above screenshot.
Head back with the injections to Mikhaila. The protagonist will automatically apply one of them and the mission will be completed. Additionally, you will receive A Friend in Need achievement / trophy.
This mission will start automatically some time after you've completed the one described above - provided that you've collected the injections and you've delivered them on time. You will receive another message from Mikhaila stating that she has arrived to Yu's office located in Talos I Lobby. She will ask you to meet her there. Once there, initiate a conversation with her. You will be rewarded with 2 Neuromods and a Suit Chipset.
Note - if you've caused doctor Dayo Igwe to reach Yu's office as well (after completing Doctor Igwe side quest), you will later receive (after getting January to the office as well) the Brain Turst achievement / trophy.
