When Isaac returns to Gravity Tether Core, an Enhanced Brute attacks him but that doesn't stop him from raising the bridges and dragging The Marker to Tether Operations B and then into The Excavation Site. However this also restores power to the Tube fans which Isaac has to hit with Stasis before passing. The Tube is protected by a pair of Guardians and has no gravity, Isaac kills some Enhanced Leapers and Lurkers before restoring power to the bridge switches using Kinesis. Nicole tells him to restore power to the bridge switches by using a Control Station at the back of a Maintenance Tube. A quarantine activates and Isaac battles Necromorphs while raising some bridges that are blocking the tracks after the quarantine lifts, Isaac raises another shutter and brings the Marker into the Gravity Tether Core. Isaac activates a monitor that raises a shutter that was blocking the Marker tracks and brings it into Gravity Tether Operations A.

Nicole tells him that the Marker must be returned to the Pedestal Chamber to 'make them whole again'. Isaac finds a replacement in the Gravity Tether Computer Room but is ambushed by Infectors and a Divider when he attempts to insert it into the relevant socket.

Isaac then slides the Marker along a set of tracks on the Landing Pad while traveling along a parallel walk way but is stopped because the door to Operations A is missing a power cell. Isaac, as instructed by Nicole, uses his Kinesis Module to slot the loader into position and unloads the Marker. Isaac Clarke and his girlfriend Nicole Brennan have taken an Executive Shuttle (that Isaac previously repaired in Chapter 10: End of Days) containing the Marker to the colony in order to contain the Hive Mind - the telepathic commander of all Necromorphs.

Isaac travels together with Nicole to the surface of Aegis VII and returns the Marker back to its pedestal in an attempt to contain the Necromorphs' controlling Hive Mind. As Isaac takes the Red Marker off the shuttle and proceeds to return it to the pedestal from which it was removed, he meets the former colonists of Aegis VII, and they will not make his duty any easier.Ĭhapter 12 takes place in the illegal CEC mining colony on Aegis VII.
