The Facility & Control Room

After the drop-in cutscene you land in the yard behind the compound. On Easy you carry the handgun, shotgun and grenade gun; on Normal or Hard you have only the handgun.

Take the left corridor to reach Gail by the broken fence, then continue.

Head north. Take the Generator Zone Key from the shelf in the far-left corner, then push the crate to the right (hold toward it) to expose a Med Pak M. Leave the room.

Go back through the door you first entered from (down and left). Rick radios in from the control room. Gail walks over — hand him the Generator Zone Key, then cross the door on the right. Follow the walkway to the split corpse; after the scene, take the Plug from the body and continue to the door at the end.

At the back are the colored levers. Ignore the battery rack in front and work the levers in this order:

Pull the side lever to bring the generator online. On the way out you hear gunfire and a scream — that is Gail. After the scene, leave.

Move forward until you see blood. Regina looks through a broken grate and calls for Gail. A Velociraptor bursts from behind the crates — kill it or it follows you. Head to the far door and out.

Cross back through the Back area to the backyard. Rick calls: he has restored the control system and wants you at the control room. Go straight ahead to the grey door and through. In the Facility Lobby, ignore the raptor sound and continue to the air duct you can climb into.

Move forward and drop through the first opening.

Grab the spinning box by the door — 9mm Parabellum — then enter.

Rick is here and opens several doors for you from his console. After the exchange, leave.

Take the right-hand corridor to the end (the left one has a green E-Box you cannot open yet), cross the door and you reach the first save room.

There is blood on the floor. On Normal or Hard the shotgun is here as a spinning box (on Easy you already have it). Grab the DDK-H Disc and a Plug, then flip the red switch on the wall to power the room. Enter the open door in the left wall (follow the blood trail) — a corpse is inside; take the Panel 2 Key (LEO).

Open the wall safe with the green light:

• PC: 0375
• PlayStation: 0426

Inside are the Entrance Key and a Sedative. Mix the sedative with another item to free a slot, then leave by the other door and save if you want.

Rick unlocks the laser barrier here but do not disable it yet. Kill the Velociraptor, then enter the first door.

Take the Code-H Disc from on top of the lockers and search the room for a Light Sedative (mix it with another sedative — on its own it is weak). Leave.

Now disable the lasers and cross the double door.

Take a look around, climb the stairs, and push the crate at the top to reveal a Sedative. Head to the only door up here to move on to the upper floor.
