Opening and the 1F backup generator

Take the Backup Generator Area Key from Materials Storage and follow Gail to the outbuilding. Arrange the batteries at the control panel, then use the separate starter switch. Retreat through the gate to get past the first raptor without spending ammunition.

Use the building’s ventilation route into Control Room Hall. Meet Rick and check the Management Office for the shotgun, H input disc and Leo panel key. The Locker Room holds the H code disc and the office locker clue. Use the Entrance Key to reach the guard post outside and take the N code disc.

Chief’s Room and B1 power

Go upstairs from the main entrance and open the H door. Collect the other panel key and the N input disc inside the office. Use both panel keys on the safe and take Key Card L. Keep clear of the window attack and shoot with the shotgun when the mouth is exposed.

The N door off the entrance leads to the Elevator Hall. Pass through the Office to the Lecture Room for the B1 Backup Generator Room Key. Return to the outdoor generator access, move the spare battery from the flashing compartment to the panel, reorder the batteries and start the generator.

First decision: Gail or Rick

Story details & possible consequences

Gail pursues Kirk through B1. Visit the Medical Room for the ID card, then take the fingerprint device and E code disc from the Strategy Room. Tom is in the Large Elevator Control Room, where you can acquire both L discs.

Rick’s route starts at the large outdoor elevator with the wounded Tom. Get both L discs, restore the Elevator Power Room and take the lift down with Rick and Tom. Move the containers in B1 Carrying Out Room, then obtain the ID card in the Medical Room and the E code disc and fingerprint device in the Strategy Room.

B1 research: gas chamber and lab lockdown

Record a matching fingerprint and create an Advanced ID Card in the Office. Use it on the smaller elevator in Elevator Hall, then enter LABORATORY downstairs. Collect the key chip in the gas chamber and obtain the right key card through the Library terminal. Use ENERGY with both E discs to enter the Experiment Simulation Room.

When lockdown triggers, Gail takes the hostile corridors while Rick’s route uses the Computer Room circuit. Collect the necessary access cards and follow the radio toward the Communication Room. Push the small crates aside in the hangar. Pick up the grenade launcher at the end of the elevated passage before facing the T. rex at the landing pad.

B3: crane, freight elevator and port

The white battery gets the next section of B3 moving. Find the C.O. Area Key and crane cards in the storage and transport areas. Clear the General Weapons Storage containers and collect the W input disc. Reach the Security Pass Room through the Rest Station and Central Stairway, stop the alarm and take the first B2 chip and S input disc.

Vent access leads into Experiment Room Hall. Get the Level C card and the W code disc in the Stabilizer Design Room. Open WATERWAY at the Rest Station and collect the second B2 chip in the Immigration Office. After the T. rex disables the freight elevator, return the white battery to the B3 generator. Get the Port Card Key and D input disc from the elevator. Give Rick the port key and collect the S code disc by the blocked port passage.

B2: Third Energy and Kirk

Rewrite both B2 chips in the Security Pass Room. Open STABILIZER and get the D code disc from the Stabilizer Experiment Room. Behind DOCTORKIRK the rewritten chips release the two gates. Extend the walkway in the Third Energy Area, solve the Power Frequency Room circuit, then run a test at the control console. Return to the scientist after the gunshot and continue toward Kirk and the Level A card.

Gail retrieves the finished Initializer and Stabilizer from Special Weapons Storage in the B3 transport area. Rick builds them with the Planning Disc and the components listed in the puzzle section. Record Kirk’s fingerprint and rewrite the Advanced ID Card in the Security Pass Room. The Initializer goes into its marked B3 module. The Stabilizer goes into its B2 module across the retractable walkway. Follow the prompts at the operating terminals and the generator in the control room, then carry the injured Gail to the Immigration Office.

All three endings: hovercraft or helicopter

Story details & possible consequences

Save in a separate slot before the final Gail/Rick choice. For Rick’s escape, leave Kirk, fill Rick’s fuel container at the Port and hold off the T. rex at the hovercraft. Gail survives. For the second hovercraft outcome, follow Gail and go straight to Kirk’s current location. Kirk survives and Gail dies.

For the helicopter route, follow Gail and visit the underground heliport first. From Central Stairway, continue along the wide corridor to the Level A door before taking the stairs. After reaching the heliport, check Kirk’s updated locator, collect him and return to the helicopter. Gail and Kirk survive. Keep the T. rex at a distance and use heavy ammunition when it exposes an opening.

Weapons, emergency boxes and bonus objectives

Upgrade the handgun with the slides from the Lounge and sights from the Library. The Management Office shotgun has parts in the Experiment Simulation Room and Stabilizer Experiment Room. The grenade launcher upgrade is behind the Level A door by Parts Storage.

Emergency boxes need plugs. Red boxes are useful for ammunition and green boxes for healing. Hemostats stop bleeding and med packs restore health. Save strong darts for dangerous enemies in tight passages. Clear the game for the first outfits, clear it again for Ancient, and record all three endings across your clear saves for the infinite grenade launcher.
