Part 13

Proceed down the hall towards a pool of water and movable objects. When the creature gets closer, use the visual cues of moving objects or footsteps in the water to aim your shotgun. Shoot the creature multiple times, then burn its body with a match to collect 1000 Green Gel.

The room on the right contains 300 Green Gel. The other room is empty.

Move through the flooded restroom and grab 1000 Green Gel in the far left corner.

In the next room, drop down and shoot the rat with a statue on its back to collect an Ordinary Key.

On the round table, find 3 Handgun Ammo and 300 Green Gel.

Smash the window of the metal closet on the side to access it and collect 5 Matches.

Move through the next room. The door straight ahead is locked and requires a key(card).

Briefly enter the room to your right to lure another invisible enemy. Backtrack to the room with movable objects and water. Align yourself behind a movable object and equip the crossbow with explosive rounds. When the creature bumps into a movable object, shoot an explosive round into the ground near it. Retreat to the room with many movable objects and repeat this process two to three times to defeat it. Alternatively, lure the creature towards an explosive bolt near a movable object.

Craft two or three new explosive bolts.

Move to the far end of the room with beds and wait at the double doors. Back away, shoot an explosive round at the floor before the door, and wait for the invisible enemy to break through and walk into the bolt. Retreat and repeat if necessary.

After defeating it, head back to the double doors. Before entering the next room, check the small red cabinet to the right for a Shotgun Shell.

Move through the next room and enter the office. On the table to your right, find 2 Shotgun Shells and 300 Green Gel. On the desk, find another 300 Green Gel and a Syringe. The Hospital Keycard is next to a corpse.

Head back to the previous room. Beware as the next door opens, revealing another invisible enemy. Use the pool of water in the middle of the room; stand at a safe distance, wait for the creature to step in it and walk towards you, then shoot it.

Backtrack to the keycard door and unlock it.

The two metal closets in front of you contain 300 Green Gel each. The small red closet at the end of the hall contains 3 Handgun Ammo.

Head down the stairs.

In the white room, a tile will disappear on three sides. Look through the first to see Leslie drawing. Press the LEFT button (with the sunflower). If you press the wrong button, spikes will eject from the floor, resulting in instant death.

Inspect the next tile to view a concrete room with a figure sobbing at a corpse. Smash all crates for random items and grab the Underground Facility Note from the small round table. Press the LEFT button, which depicts a picture with only three gear wheels.

Inspect the last peekhole and enter the room. The shelves hold 300 Green Gel, and the desk contains the Audio Tape - Assimilated Consciousness. Inspect the painting on the wall depicting a neuron with an overgrown synapse. Press the RIGHT button.

This unlocks a fourth, final door. Go through it, grab 1000 Green Gel from the rack on your left, and head through the next door.

After the cutscene (a non-interactive cinematic the game plays automatically), search the room for 300 Green Gel and heal Joseph.

Head through the double doors and turn right. Note the oil spot and enter the storage room. The lockers contain 2 Shotgun Shells, 300 Green Gel, and 2 Handgun Ammo.

Exit the storage room and move to the other side of the area. Regular enemies will appear. Rush back to the oil spot and stand behind it. Set it on fire when the closest enemy is a couple of meters away. Kill any remaining enemies with your handgun and matches.

Move to the back of the medical room and smash the closet to collect 4 Handgun Ammo.

Enter the dark area, note the flammable barrel, and enter the door on your left. Burn the 'corpse' hanging from the ceiling.

The small red closet contains 3 Handgun Ammo, and the white closet contains a Harpoon Bolt. The back of the room contains 300 Green Gel and a Syringe.

Head downstairs and have Joseph dismantle the bomb, then enter the room to trigger a cutscene.

Climb the long ladder and inspect the next room for 3 Matches and 3 Shotgun Shells in the cabinets, and Map Fragment 9 in the corner.
