Run down the corridor and head through the door. Pick up the battery here in the middle of the room with Kinesis and place it in the plug to open the door. Advance through the door and head right at the fork. Run down the left path to find some ammo, then return down the opposite way. The path winds around, leading to a locked door. Ignore it for now and take the path to the right, following the walkway with grating on the floor.
After crossing through the two areas you'll find a power node. Turn around to face advancing necromorophs. Run past their corpses and take a right to come to a room with a large cord in the center. There's a batter waiting here. Pick it up with Kinesis and slot it into the console nearby. You'll have to fight off advancing enemies first, or else the battery will continually be knocked out of your grasp. You'll need to follow the path around to the original room,so be careful when carrying the battery. Once it's in, turn around and run through the pathway with white grating.
Continue on until crawlers assault you. Eliminate them and get back on track. There's a battery up ahead. Wak forward to another pathway with white grating while you wrap around to the room with two batteries. Insert this battery. The door in the center will open. Go through it and walk straight until you reach a room with a Peng sign. Go through the doorway to the left, but be sure to grab the power node in the box beside the door. Turn around and exit through the previous room, then on to a door to the right of a red "authorized personnel" sign.
Once you run through, take the left path. Keep running straight through a corridor with red machinery dotting the halls. Run straight, following the advancing catawalk as it eventually curves right. There's a cacheof goodies here through the door that will cost you a power node. Leave the room and get back on the path, this time heading straight down the same catwalk. Take your first right, and then right again. You'll see Vandal come face to face with a mirror image of herself, which soon turns to that of a necromorph. Kill it, and then run forward through the lockdown.
Once you're free to advance, run back down the catwalk so the green light and tinted fog are on your left. Head through the door, across the gated walkway, and turn left to run through the door. Enter the train in this area. You've got another grisly battle ahead of you. Once it's done, you've reached the chapter's end.
