As you start chapter 5 you will be in the presence of a save station (ss14).Save the game if you wish to do so and then when you are good to go, enter the door to the right.
You will enter a series of cryogenic storage rooms. The rooms are identical and the first two are completely without baddies or any points of interest so continue through until you reach the third freezing room. Upon entering the room, cruise up to the windows in front of you and pick up the text log here (Log 17 - Thawed Bodies). Continue to the next cryo room.
In the fourth cryo room, go down the left hand hallway, a spitter will jump out of one of the glass tanks located here, again continue forward and into the fifth freezer room. As you enter a slasher will jump out of one of the tubes in front of you and a spitter will enter from the left hand doorway. After killing these two venture into either one of the side halls and another two slashers will appear, one from each hallway. Once they are dead, kill the final slasher hanging out near the exit door and head on through to the next area.
Immediately after you enter this room look on the console directly in front of you and you will find a text log (Log 18 - Stuck Coffins). Make your way to the opposite side of the room and take the elevator down to the lower level to find a gravity core spinning away. Before we get started on the puzzle here, look on the shelf to the right of the gravity core to find a schematic (Schematic 6 - Ripper). Pick up the power node (14) from the bench next to the blue hackable terminal, and then hack said terminal.
After the terminal has been hacked, you will notice some hatches open either side of the core. You will need to use stasis on the spinning core before using kinesis to pull the levers inside each of the hatches down. Pulling both levers down will cause another pair of hatches to open, so repeat the process and then again for a third set of hatches - being sure to re-use stasis on the core if it returns to normal speed (this will cause the hatches to de-activate after ashort time if you are too slow). Once the three sets of switches have been activated, the room should lose gravity.
Float upwards and use stasis to slow the spinning fan blade and then boost through when you are able. Fly up to the top of the room, and use stasis on the circular door here. After the debris falls through and before it closes, boost upwards through it. At the very top of this room you will find a schematic (Schematic 7 - Medium Med-kit). Land on the platform here and re-activate the artificial gravity by hitting the console. Enter the unlocked door.
Here you will find a shop to your right. Further up the stairs you will find abench to upgrade your equipment if you so desire and opposite the bench is asave station (ss15) and a vent leading to the next area (you will need to usekinesis to move the hanging objects to activate both of these). When you areready to continue jump into the vent and crawl through it to the next section.
After the vent section, open the door in front of you look behind the stack of crates directly in front of you to find a schematic (Schematic 7 - Line Racks) on the shelf behind it. Make your way over to the left side of the room and exit via the door here. Follow the hallway around the corner and you will be ambushed by a pair of lurkers, these little guys will hang from ceilings, walls or even chill at ground level and fire projectiles at you from the three tentacles protruding from their backs. To kill them, simply sever a couple of their tentacles as they are preparing to fire at you.
Once the lurkers have been dealt with, continue to the ramp at the end of the corridor, kill the slasher that appears here and continue upwards and through the door at the top of the ramp. Continue until you reach a large room with a large, blue stained glass window on the far end and a pair of stairs flanking you.
As you move into the room here you will be ambushed by a tripod, fire on its weak spots when you get the chance and if you are successful in damaging it enough it will retreat temporarily. Don't breathe a sigh of relief just yet though as now you will be set upon by a large group of the pack, once they have been successfully fended off, continue forward towards the blue window and kill the slasher here.
Climb the set of stairs on the right side of the room when looking at the blue stained glass window and follow the balcony towards the area opposite the entry point. Kill the exploder here and kill the two slashers that decide to jump in on you from the windows to the right (one from the second window and one from the final window), once they are dead another couple of slashers and a spitter will make their way over to you from the opposite balcony . Defeat them all, if you feel like killing some more necromorphs, cruise over to the opposing balcony and kill the exploder and the slasher that jump through windows here. Either way once you have looted everything you can, continue through the door at the back of the room.
Defeat the crawling spitter and press on through the next door. Make your way around the marker statue here and into the elevator when you are able to do so. Keep a weapon handy during this elevator ride as a slasher will break through the ceiling as you reach the top. Kill it and exit the lift.
Continue through the corridor until you reach an open waiting area with a large window to the outside on the left. Enter the door on the right to find a power node (15), a schematic (Schematic 8 - Detonator) and a save station (ss16).Save the game if you wish, then continue onwards through the waiting area and through the corridor to the right. Enter the door here for a quick scene during which you will need to mash the button prompt on the screen to continue.
It's not over yet though, as soon as you regain control of Isaac, he will be targeted by the tormentor - some kind of super-necromorph that kind of looks like a combination of a brute and a tripod. During the first stage, when it traps you and picks you up make sure you shoot the weak spot on its arm when you get the chance to do so or you will die. Once the tormenter has thrown you aside, it will chase you. So use stasis on it then use kinesis to move aside the sliding object in front of you and sprint to the window in the distance.
Eventually, following the scene, you will be out in space hanging off the side of a gunship with the tormentor. You should see some floating red canisters,shoot one of these to kill the tormentor and complete the level.
Note: For defeating the tormentor you will earn the achievement/trophy 'Tormentme No More'.
