Communications & Helipad

Both routes end at the same scene — Gail holding Dr. Kirk at gunpoint, sending you off to call a rescue chopper.

• With Gail: fight back through the Research Zone, Library, Main Hall B1, Vestibule B1 and the Material Transport Vestibule (two dinos per room — sleep or flee the ones you can), then through the double door.
• With Rick: at the big computer in the Simulation Room, Rick works out the hatch code. It is a random memory code — you get two attempts and must enter three codes, so write them down. Clear it to cross the hatch; fail and you walk the long way to Testing Room B1.

Material Transport Vestibule → B1 Backup Generator Room → up the ladder → Facility Backyard → far door → Office Vestibule (raptor) → Main Entrance → right double door → Management Office Vestibule → the bloody door → Management Office (save) → the other door → Control Room Lobby → Control Room (1F): the elevator works now — ride it.

Grab the Slag Bullets (red E-Box optional). On the right-hand wall near the door, use the red device to take the Antenna Activation Key. Leave by that door and save.

Communications Zone Passage → far door → Communication Antenna Room: the control desk has a cover just like the box the key came from — use the key here and the large antenna rises. Leave.

Heavy footsteps, Rick radios in, and the second T-Rex attacks.

T-Rex — Second Encounter

Difficulty

The T-Rex intercepts you in the passage as you head back from raising the antenna. It is a scripted chase — you only need to reach the door Rick opens, not to win the fight.

Expand

Attacks

• Bite lunge while you run
• Blocks the corridor

Strategy

• This is a chase, not a fight. Sprint to the far end of the passage.
• From there, fire the shotgun or grenade gun at it until Rick opens the door.
• Cross through and you are safe — do not try to kill it.

Regina radios Roger: the mission is done, the only survivor is the Doctor, send a chopper fast. Rick marks your destination.

Main Entrance → the giant double door → Front Entrance: Pteranodons are massing — sprint the corridor and into the big end door (open now) → Helipad Passage: shoot the two raptors and take the right-hand door → Aircraft Hangar.

Climb the ladder and walk to the end of the upper hall: the Grenade Gun (Normal/Hard) or Grenades (Easy). Come back down — crates block the lower path. Push them in this order (leave and re-enter if you make a mistake):

The path clears. Take the Grenades at the far door and cross.
