Third Energy & Final Escape

• With Gail: Kirk's Lab → run via the B3 Control Room to the General Weapons Storehouse; take the "Security Level A" door in the Transport Passage, then the right-hand door at the end of the hall → use the elevator, go up → grab the ready-made Initializer and Stabilizer → run to the Security Passes Room.
• With Rick: Kirk's Lab hands you a Project Disc; unlock the door → Third Energy Zone B2 → run to the Parts Warehouse: take the Grenade Gun Parts at the far end; at the center computer use the Project Disc, code 367204 → Central Part 1 and Central Part 2 → P.S. Experiments → Stabilizer Design Room: far computer, Project Disc, code 0367 → Protective Part 1-B; the circular computer, Project Disc, code 0204 → Protective Part 2-A and Protective Part 1-A → P.S. Experiments → other double door → Stabilizer Experiment Room: second part, use the Project Disc at the shelf → Projector Part 2-B; at the assembly computer (the one with the big tube) use any part to build the Initializer and the Stabilizer → run to the Security Passes Room.

On the computer near the corpse use the ID Card, code 78814 (PC) / 31415 (PlayStation), apply the fingerprint, rewrite the data → exit by the blue-device door and save. (If you went with Gail, grab the Grenade Gun Parts in the Parts Warehouse now — they kill its reload delay.) → Passage → far door → Third Energy Zone B2.

The computer works now — it lets you register the Initializer and the Stabilizer. Head back out.

Cross the bridge, hit the far switch and set the Stabilizer. Leave the bridge, take the right-hand path (open neither door) and ride the lift down → Third Energy Zone B3: up the stairs, down the next; mid-path, hit the switch and set the Initializer; go to the end and activate the computer → back to Third Energy Zone B2: cross the bridge again and activate this computer. The overload begins.

In the cutscene the ceiling nearly crushes Kirk; Gail shoves him clear but a pipe pins Gail, who tags Kirk with a tracker. You are moved automatically to the Third Energy Control Room.

Door opposite the computer → C.E. Power Room (raptor maybe) → Personal Lab Passage (raptor maybe) → Kirk's Personal Lab → the door you have not used → Kirk's Library: Gail, badly hurt, talks about Kirk and then blacks out. Carry him to the Landing Room. Rick clears the way — running is the only option left.

Landing Room → Rest Station → Testing Room Passage (two Therizinosaurus) → Testing Room B3 → B3 Control Room → other door → General Weapons Storehouse → metal shutter → Transport Passage → the right-hand "A" door → back into the General Weapons Storehouse: Gail and Kirk. Gail hands over a disc, then dies; Regina decks Kirk.

Landing Room → save → Port Passage → far door → Port: the T-Rex is there but dormant — take the only open door (it wakes as you do) → Hovercraft Storehouse: board the Vortex, grab the floor Grenades, leave → Canal: fire on the T-Rex while you can. In the finale Regina rigs an explosive, feeds it into the T-Rex's mouth and detonates it.

T-Rex — Final Fight

Difficulty

The real showdown. The T-Rex rams the escape craft on the water and every exit locks — there is no running now, so keep it circling and hit it hard until the finish triggers.

Expand

Attacks

• Charging bite
• Roar lock
• Rams the escape craft

Strategy

• Keep circling and only fire on the FIRE / attack prompt — the grenade gun is the weapon.
• Take every round the team throws you before the fight seals the doors.
• The kill is scripted once you have dealt enough damage; survive the window.

Debrief: Kirk — Detained · Gail — Deceased (sacrificed himself) · Rick — Alive · Regina — Alive · Tom — Deceased · Copper — Unknown.

Landing Room: Regina blocks Gail; Rick approves → follow them → save → Port Passage: far end, auto door (optional Multiplier), far door → Port: circle to the only door, beside the big metal shutter → Hovercraft Storehouse: Gail is wounded in a chair; down the ladder, right — the craft needs fuel and Rick gives you an Energy Tank → back to the Port, save → circle to the red barrels, use the Energy Tank → Nucleum → back to the Hovercraft Storehouse, down, right, give Rick the fuel. The T-Rex is heard; Rick tosses you grenade-gun ammo — take it all.

Cutscene: the T-Rex bursts a gate and every door seals. Keep running and circling; on FIRE, hit it with the grenade gun. In the finale Rick rockets it, the blast triggers the overload, and they escape by Vortex.

Debrief: Kirk — Unknown (not captured) · Gail — Alive (recovering) · Rick — Alive · Regina — Alive · Tom — Deceased · Copper — Unknown.

Take the same route but ignore your map marker after the Landing Room: Rest Station → Testing Room Passage → Testing Room B3 → B3 Control Room (save) → General Weapons Storehouse → metal shutter → Transport Passage → the "A" door straight ahead (not the right one) → Transport Helipad Passage → ride the cable car to the far side → the "A" door → Underground Helipad.

• If you chose Gail: first back out and ride the cable car again → Transport Passage → now the right-hand "A" door → Stabilizer Experiment Room: Kirk and Gail; you get a disc and Regina drags Kirk to the Underground Helipad → board the helicopter, grab the floor Grenades.
• If you chose Rick: at the Underground Helipad, Kirk is trying to take the helicopter; Regina grabs him from behind, he turns with the gun, she kicks him out cold → grab every Grenade.

Ride out on the cable car with Rick; fire the grenade gun at the T-Rex until it quits. In the finale the group escapes by helicopter and Rick drops a bomb on the T-Rex.

Debrief: Kirk — Unknown (later reported detained in high military ranks) · Gail — Alive (recovering) · Rick — Alive · Regina — Alive · Tom — Deceased · Copper — Unknown.
