It is on his way back to the Main Engineering Control Room that Isaac discovers the source of the holes in the corridor - a Drag Tentacle. In order to leave the room, he had to not only battle the Necromorphs, but also avoid a spinning mechanical appendage while conserving a limited oxygen supply. Isaac interacts with a monitor that activates the Centrifuge via his RIG which also removes the oxygen from the room. After killing another pair of Leapers, Isaac uses his Stasis Module to slow the spinning roters down on a pair of clutches and uses his Kinesis Module to insert them into the Centrifuge which prompts more Leapers to attack. There are two spherical holes that are torn through a corridor that Isaac passes through on his way to the Gravity Centifuge which he enters in Zero Gravity. He takes an elevator towards the Centrifuge and, while passing through a decontamination room, is attacked by Leapers and Slashers. When Isaac returns to the Main Engineering Room, an Infector turns a corpse into an Enhanced Slasher. Had Temple not fixed them before Isaac's arrival, it would be up to him to do it.

A large number of Slashers and Enhanced Slasher ambushed Isaac once he exits the Gondola. When he activates the second engine refueling switch, he finds another audio log from Temple who believes that someone (possibly a unitologist) sabotaged the fuel lines. After refueling the 1st Engine using Kinesis to pull a switch down, Isaac has to use a Gondola to gain access to the 2nd Engine refueling switch. In the main Engineering room, Isaac finds an audio log created by an engineer named Jacob Temple who is trying to fix the same problems as Isaac. When Isaac exits the tram that he boarded at the end of Chapter 2, Hammond tells him that the Engines are offline because they have no fuel and the Gravity Centrifuge is offline meaning that trillions of tons of rock from the planet crack are pulling the Ishimura toward Aegis VII. Isaac's new objective is to solve these problems.
