Perdition

Due to the breach in the dome, the Arboretum is now a microgravity environment. Use your propulsion system to maneuver while avoiding the Apex Tendrils. Scan these tendrils three times to complete the research for this organism. Coming in contact with these tendrils causes damage, so constantly monitor your surroundings and avoid touching these black tentacle-like appendages.

Psychotronics

Containment

Access Psychotronics via the Talos I Lobby. Along the way, stop by Hans Kelstrup’s office, in the Atrium, and use the Fabricator to create the Prototype Nullwave Device. A waypoint marker appears on the HUD leading you to the heart of the Coral, located in the massive containment chamber. The chamber can be entered from a hatch near the entrance to the G.U.T.S. Access Containment via the Atrium. Then proceed to the chamber entrance by passing through Live Exam. Be prepared to encounter multiple Typhon enemies along the way, including a Voltaic Phantom, a Weaver, and a few Mimics. Apex tendrils have also penetrated Psychotronics, so avoid making contact.

Eliminate the Cystoid Nest near the containment chamber’s entry point, then step into the micro-gravity environment. Maneuver toward the spherical object in the center of the chamber and install the Nullwave Device. Once you’ve installed the device, exit the chamber and enter the G.U.T.S., heading toward the Cargo Bay. From there, you can access Life Support and proceed to the Power Plant.

Power Plant

Reactor

Unless you eliminated them earlier, the reactor room is still occupied by two turret-wielding Technopaths. Apex tendrils pose a threat as well. Stay low and try to avoid detection as you drop to the ground floor. The waypoint marker leads you to a maintenance access panel on the floor in front of the control room. Open this panel and push the button found inside—a hatch opens nearby giving you access to the self-destruct consoles in the reactor chamber.

Interact with the self-destruct console, inserting Morgan’s arming key on the left and Alex’s arming key on the right. Once the keys are inserted, they must be turned to arm the self-destruct mechanism. The actual self-destruct sequence must be initiated from the Bridge. Backtrack through the Power Plant and Life Support to reach the main lift, then ride it to the Arboretum. From there, access the Grav Shaft leading to the Bridge.

Talos I Bridge

Foyer

If you incapacitated Dahl and removed his Neuromod, you’re contacted by Mikhaila and Dr. Igwe as you access the Bridge. Igwe reports Dahl is recovering and that they’re making their way to the Shuttle Bay. If you choose to destroy the station, you can join them in command shuttle to escape. The Bridge is surprisingly calm. So take your time to explore before making your big decision. Search Matt Cothron’s body slumped over the nearby railing to retrieve some ammo and a Silenced Pistol Ammo fabrication license. Next, grab one of the nearby turrets and enter the Grav Shaft leading down to the Escape Pod Bay.

Escape Pod Bay

Exit the Grav Shaft and deploy the turret, allowing it to engage a few Cystoid Nests and Cystoids. Like the other escape pod bays you’ve visited, this one is filled with the bodies of crew members who were unable to escape the station. Search the briefcase near Sadie Hall and Gordon Bitz’s body to retrieve a Scope Chipset and an EMP Charge fabrication license. Once you’re finished searching this area, return to the Grav Shaft and enter the Command Deck.

Command Deck

If you saved Alex back in the Arboretum, you find him standing at the entrance to the Command Deck, urging you to use the Nullwave Device to stop the Typhon. If Alex died, you’ll find January here instead, urging you to destroy Talos I. These decisions can be put off a bit longer.

Continue exploring the Command Deck at your leisure. Search Omar Bolivar’s body to retrieve the keycard to the Briefing Room.

Access the security station near the Command Deck’s entrance to download a map of the Bridge. Grab Matt Cothron’s TranScribe and an EMP Charge nearby. Alika James’ TranScribe can be found on the nearby console. Play the recording (Checking on an SOS) found on Alika James’ TranScribe to automatically complete the Where is Kirk? optional objective (you already found what became of Kirk Remmer).

Where is Kirk? Objective Summary: Based on some message I overheard, a crew member named Kirk Remmer is in danger. If you haven’t found Kirk Remmer yet, he’s been transformed into a Phantom, located in Life Support’s Escape Pod Bay. Eliminate the Phantom and search its remains to complete this objective.

Briefing Room

Use the keycard retrieved from Omar Bolivar to open the door to the Briefing Room. Alternatively, you can simply break one of the windows and step inside. This room contains a safe and it only requires Hacking I to crack. Access the safe to grab two Neuromods, a Nullwave Transmitter, and a Weapon Upgrade Kit. If you don’t have the Hacking I ability, you can find the safe’s password on a note in Captain’s Loft. Judging by all the food on the table, it looks like there was some sort of party held in the Briefing Room prior to the Typhon containment breach. Search Skye Braxton’s body to retrieve a Scope Chipset.

Captain’s Loft

Head upstairs to the Captain’s Loft. Search Bill Nixon-Greene’s body (on the sofa) to retrieve another keycard to the Briefing Room. The briefcase next to his body contains a Scope Chipset. Next, locate Jada Marks. Search her body to retrieve her TranScribe, a Neuromod, and a keycard to her cabin in Crew Quarters. Lift the notebook on the nearby desk to reveal a note containing the keycode to the Bridge safe in the Briefing Room.

Shuttle “Advent” Objective Summary: The shuttle “Advent” left Talos with five crew aboard and is heading for Earth on a routine trip. They might have departed before the Typhon broke containment, but there’s a good chance they’re carrying Typhon. I have the ability to detonate the shuttle remotely. Listen to Captain Marks’ Dilemma, one of the audio recordings found on Jada Marks’ TranScribe, to trigger this optional objective. Turn to the nearby console showing the shuttle’s status. It’s scheduled to arrive at a landing facility in Seattle within a few minutes. Doing nothing allows the shuttle to land, potentially leading to a Typhon infestation of Earth. Or you can trigger remote charges on the shuttle to destroy it, killing everyone on board, along with any Typhon-tainted cargo. If you were attempting to make it through the game without killing any humans, detonating the shuttle prevents you from earning the Do No Harm achievement/trophy. But if you don’t detonate the shuttle, there’s a chance the Typhon will reach Earth. The choice is yours.

Finale: A Mind Without Limits

If you choose to eliminate the Typhon with the Nullwave Device, interact with the console on the Command Deck, next to Alex or January. If present, January won’t let you activate the Nullwave device, You must destroy January to proceed. Alex, on the other hand, is more than happy with this decision. Activating the device triggers a powerful Nullwave pulse within the heart of the Coral, located in Psychotronics. The cascading effect eliminates all the Typhon organisms, including the Apex Typhon, leaving Talos I unscathed.

Finale: Perdition

If you’d rather follow January’s directive and destroy Talos I, access the command console in the Captain’s Loft to trigger the self-destruct sequence. This starts an eight-minute timer, giving you plenty of time to escape. Returning downstairs, Alex is disappointed by your decision to destroy Talos I. But he’s staying put. You can’t force him to evacuate by dragging him to the command shuttle or his escape pod. What’s your decision? Will you stay aboard and go down with the station, as directed by January? Or will you escape?

Escape: Alex’s Escape Pod

Alex’s escape pod, located atop his office in the Arboretum, offers the quickest way off the station. If you retrieved the EP101 keycard from Alex’s suite in Crew Quarters, you can enter the escape pod. The microgravity in the Arboretum eschews the need to access Alex’s workstation in his office to extend the bridge. Simply thrust toward the escape pod, insert the keycard, and hop inside, careful to close the door behind you. Launch the escape pod to vacate Talos I before the station explodes.

Escape: Dahl’s Command Shuttle

Dahl contacts you after you initiate the self-destruct sequence. This completes the Incapacitate Dahl optional objective. Dahl’s shuttle is ready to evacuate Talos I. His command shuttle will leave approximately 50 seconds before the station explodes. Race through the Arboretum to the main lift and take it down to the Talos I Lobby. From the lobby, make a beeline for the Shuttle Bay. Watch out for two Voltaic Phantoms and some Mimics near the command shuttle jetway. Fight your way past these threats, then enter the command shuttle.

If you saved them, you’ll find Aaron Ingram, Sarah Elazar, Dr. Igwe, and Mikhaila Ilyushin in the shuttle’s cabin. If time allows, speak to each of them. Also, don’t forget to search the shuttle’s cargo hold, using the keycard you swiped from Dahl. Here you find a crate containing two Recycler Charges and two Neuromods.

When you’re ready to leave, enter the cockpit and sit in the seat next to Dahl. Within seconds, the command shuttle leaves Talos I, just before the station explodes.

Epilogue

Regardless of how you choose to end the game, Morgan awakes in a secret location surrounded by Alex and four distinct Operators. The Operators speak with the voices of Mikhaila Ilyushin, Dr. Igwe, Sarah Elazar, and Danielle Sho. Here you undergo a debriefing, with each Operator providing input on your performance. Did you use any Typhon Neuromods? How many people did you save? Did you kill the cook imposter? Did you destroy Talos I or did you simply eliminate the Typhon with the Nullwave Device? Each Operator has a say in whether you should live or die. If they allow you to live, you have one last decision. Will you take Alex’s hand? Or will you kill them all?
