You'll be in the same room and are greeted by a new Necromorph: immortal spawns that cannot be killed. Your only option is to do enough damage to take down their limbs and stasis them quickly. Eventually these enemies will regenerate back to perfect condition. However, while it's down and slowed take the time hack the nearby panel and move ahead.
Grab the Power Node to the right. Clear out any killable Necromorphs and continue on. In the next room will be a regenerating enemy and another corpse/door puzzle. Stasis the Necromorph and grab the body to move to the next hallway.
Kill more enemies and get ready of the zero gravity section. It's not only a deadly maze, but there is also no oxygen. This might be the first time in the game where the Air upgrade might actually come to use. Stasis the first set of obstructions to move in deeper.
There will be more obstacles, but most of the them can be taken down with stasis. Towards the end of the frantic space swim is a Lobber. Take it down fast with a strong shot of the Contact Beam or another ranged weapon. Once it's dead, descend back down and turn on the gravity. Proceed through the door to reach the last chapter.
