I will need to keep the robot with me as I venture through the Mechanist's lair to be able to access the doors. Then I will be able to gain access to the Mechanist's lair. I need to use the robot workbench to install the M-SAT into a robot of my choice. I should speak to Ada about my next move. I discovered the Mechanist's lair has a hidden entrance in the old RobCo Sales and Service building. Ada will also thank the player character, at which point the main storyline of Automatron is complete. She will usually also give the side quest Rogue Robot. She will then thank the Sole Survivor, before giving them her costume and walking away. After explaining herself, she will remove her helmet, revealing herself to be Isabel Cruz. The dialogue here is timed, so if one waits too long to speak with the Mechanist, she will turn hostile. Once the Duelbot has been defeated, the power will fail and a speech check will allow the player character to make the Mechanist stand down.

(See notes below on where the holotapes are.) At this point the player character can go up to the control room, surprise the Mechanist and a speech check will allow the player character to make the Mechanist stand down. After unlocking the terminal, then inserting each supervisor holotape and playing them, the three voice authorizations will override the lockdown and the elevator will work. Next to it on the wall is a Master-level locked 'elevator access terminal' that can manually override the lockdown. In this room is an elevator that is initially not working. This room can be accessed either by a locked door on one side or a hole in the wall on the other. If going all the way back to near the beginning of the lair, where the first set of robots were fought, there is a decontamination corridor with a security room overlooking it. Gradually, however, as announced by a machine-generated voice, and as more and more robots are defeated, the power consumption approaches maximum capacity and then the power fails.Īlternatively, the player character can collect all three supervisor holotapes and before going into the war room, the final battle with the waves of robots can be avoided. At one point, the Mechanist advises the player character that the fight is hopeless, because more robots can be created for every one defeated.

Inside, they will battle several waves of increasingly tough robots, the last one being a Duelbot.

After a lot of battling, the player character will finally make it into the Mechanist's war room.

Once inside, the player character must use their robot, with an attached M-SAT, on several devices stuck to walls, to open the blast-proof doors throughout the lair. The Sole Survivor is tasked with finding and stopping the Mechanist once and for all, so head to the RobCo Sales & Service Center where The Mechanist's lair is hidden.
