This Rapture Departure Protocol set the machine to find a way to escape the failing city on its own. At their exit, he discovers an audio diary revealing Porter had set a hidden protocol for The Thinker before being arrested by Andrew Ryan's men.

Reaching the Core, Wahl locks the main access, forcing Sigma to pursue him through the Access Shafts. More important to Sigma, the Thinker is also the key to the mysteries surrounding his own identity, and Porter's reappearance in Minerva's Den after being framed by his former colleague and imprisoned at Persephone 10 years previous. Once it has been done, Sigma reaches the Computer Core sector where The Thinker awaits, but so does Wahl, whose equation has not yet predicted the outcome of their final confrontation. This is important to their escape plan, as the reprogrammed beacon will render Porter's private bathysphere invisible to the torpedo launchers set by Sofia Lamb to prevent anyone from leaving Rapture. Porter, on the other hand, was using it for a more personal purpose: to have The Thinker emulate the voice and personality of his long-dead wife Pearl, his grief for whom he was never able to overcome, even after coming to Rapture.Īt Operations, Sigma is asked by Porter to salvage a signal beacon from a sunken bathysphere in the nearby junkyard outside the building, and then to reprogram it in Wahl's office in the Programming wing.

Wahl wanted to use the machine's remarkable computing power to generate an algorithm capable of predicting anything. Once all those tasks are done, Sigma can finally continue on his way to Wahl and The Thinker.Īlong the way, it is revealed to Sigma that the two founders of Rapture Central Computing had opposing visions of how The Thinker should be used. Another detour is then needed into McClendon Robotics to retrieve both that genetic enhancement and a Hack Tool.

According to the Thinker's records, the Plasmid can be found at the Air-Tite Archives, but first, an Electro Bolt Plasmid is required to force open a malfunctioning entrance door. After the punch card is recovered, the Operations Access is still blocked by a magnetic lock, which can only be removed through the use of the Gravity Well Plasmid. This is required to access the Computer Core through the Operations sector. After restoring the main power to this part of the complex, Sigma heads to the Executive Wing to retrieve the Operations Access Punchcard hidden in Porter's office. Reaching the main entrance in complete darkness, he finds that Wahl has posted several Splicers to stop him. Guided by Charles Milton Porter, Sigma enters the Minerva's Den facility through a maintenance access airlock. Tenenbaum seeks The Thinker's computing capabilities to synthesize a cure for the effects of ADAM on Rapture's remaining spliced population and sent Sigma to Porter in order to recover the computer's code. After regaining consciousness, Sigma is contacted by Porter, who is looking for help to retrieve a copy of The Thinker's programming code, his life-work, which he wishes to take with him when escaping to the surface. Reed Wahl, seeing Sigma's arrival with dread, detonates the tunnel access to Minerva's Den through which Sigma was walking, sending him to the ocean floor. In 1968, a newly reactivated Subject Sigma is making his way to Minerva's Den.

Minerva's Den shows a new side of Rapture within Minerva's Den, the high technology district of the city, and explores the backstory of The Thinker, a supercomputer responsible for the control of many automatic devices and systems in the underwater metropolis, and its creator Charles Milton Porter.
