Golden Armor — Complete Route
The Golden Armor is the single most important endgame item. Without it, you cannot enter the Artifact Chamber and cannot complete the game.
Step-by-Step Path
| Step | Location | Action |
|---|---|---|
| 1 | Bunker Residential Entrance | Find the bunker entrance (green circle on map, near the large lake) |
| 2 | Guest Keycard | Inside the bunker — it's on a desk in the first office area |
| 3 | Maintenance Keycard | From the Shovel bunker (southwest of the island) |
| 4 | Golden Armor Room | Requires Guest Keycard. Located in the lower level of Bunker Residential |
| 5 | Equip armor | It goes in the armor/accessory slot. Once equipped, it protects you from the artifact room's lethal radiation |
Climbing gear note: You need the Climbing Rope (#2 knot shortcut) to access some vertical sections of the bunker. Craft it from 3 ropes.
Final Cave — The Laboratory Descent
The final cave is a massive 4-level laboratory beneath the island's central mountain. Enter through the giant metal door near the helicopter crash site (requires Keycard C).
Level 1: The Descent
| Section | Enemies | Hazards | Strategy |
|---|---|---|---|
| Initial drop | None | 50m fall (use rope) | Repel down carefully |
| Corridor A | Armsy (mutant arms) | Tight spaces | Shotgun + dodge backwards |
| Holding cells | Virginia mutants (×4-6) | Open area, multiple entry points | Grenade the group, pick off survivors |
| Elevator shaft | Fingers mutants | Drop attack from ceiling | Listen for growling — look up before entering |
| Level 1 exit | None | Keycard A door | Use Keycard A |
Level 2: The Laboratory
| Section | Enemies | Hazards | Strategy |
|---|---|---|---|
| Flooded corridor | Drowned mutants | Underwater rebreather sections | Use rebreather, swim FAST |
| Containment breach | Mutant dogs + flying squid mutants | Darkness, no lights | Night vision or flashlight |
| Central atrium | 2x Armsy + Fingers | Open 3-story atrium | Use the high ground. Snipe from the catwalk |
| Cryo chambers | Frozen mutants (don't break glass!) | Breaking glass awakens everything | Walk carefully around cryo tubes |
| Lab exit | None | Keycard B door | Use Keycard B |
Level 3: The Reactor
| Section | Enemies | Hazards | Strategy |
|---|---|---|---|
| Reactor core entrance | None | Radiation (wear Tech Mesh) | Move fast through contaminated areas |
| Power coupling puzzle | 3x Fingers mutants | 3 couplings must be removed simultaneously | Use time bombs to sync the destruction |
| Cooling tunnels | Mega-Fingers boss | Tight tunnels, boss chases you | Kite backwards, shoot weak point (glowing sac on its belly) |
| Boss arena | Mega-Fingers + adds | Large chamber with pillars | Use pillars for cover. Aim for the glowing belly sac |
Mega-Fingers Boss Strategy: - Phase 1: Boss charges in straight lines. Side-step and shoot the glowing belly - Phase 2 (below 50% HP): Boss spawns smaller Fingers adds. Grenade them immediately - Phase 3 (below 25%): Boss enrages — faster charges and wider hitbox. Use the environment pillars - Kill reward: Drops the Artifact (3 modes — see Endings below)
Level 4: The Artifact Chamber
| Section | Requirements | Enemies | Reward |
|---|---|---|---|
| Entry door | Golden Armor equipped | 0 (radiation kills without armor) | Chamber access |
| Artifact pedestal | Artifact from Mega-Fingers | 0 | Place artifact to choose ending |
Multiple Endings
After defeating Mega-Fingers and collecting the Artifact, descend to Level 4 with your Golden Armor. The Artifact has 3 modes that produce 3 different endings:
Ending A: Escape (Sky Mode)
| Mode Activation | Cutscene | Outcome |
|---|---|---|
| Place Artifact in Sky position (upward) | Helicopter arrives within 60 seconds | You and Kelvin/Virginia escape on a helicopter. The island is sealed. |
Requirements: Must have kept both Kelvin and Virginia alive through the game.
Good ending cutscene: The helicopter flies over the island as the facility collapses. End credits show your character back in civilization.
Ending B: Destroy (Fire Mode)
| Mode Activation | Cutscene | Outcome |
|---|---|---|
| Place Artifact in Fire position (red/downward) | Explosion sequence triggers | The entire facility and island are destroyed. You presumably die in the explosion. |
Requirements: None — can do alone.
Bad ending cutscene: Massive explosion from the center of the island. The screen fades to white.
Ending C: Power (Cube Mode)
| Mode Activation | Cutscene | Outcome |
|---|---|---|
| Place Artifact in Cube position (neutral/center) | Defense grid activates | You become the island's new guardian. The facility's automated defenses activate, purging all mutants. You rule the island. |
Secret ending cutscene: You sit on a throne in the control room as the defense grid fires. The island becomes a fortress under your command. Post-credits scene shows a new mutant species emerging from the ocean (sequel setup).

Pro Endgame Tips
- Golden Armor first: Make the Golden Armor your primary objective once you have Keycard A. It opens the entire final sequence. Don't explore every bunker first — the armor is priority #1.
- Time bombs for bosses: Craft 5-10 time bombs before entering the final cave. The Mega-Fingers boss takes 3x damage from explosives. A well-placed time bomb does 200+ damage.
- Virginia's trust: Max her trust before the final cave. At trust level 4, she gives you a unique weapon (machine gun pistols). She also provides covering fire during the final boss.
- Kelvin's notebook: Kelvin takes notes throughout the game. Read his notebook after each bunker to piece together the lore. His final entry changes based on your ending choice.
- Save prep: Create a hard save BEFORE entering the artifact chamber. This lets you replay all 3 endings without re-fighting Mega-Fingers.
- The "secret" purple bunker: There's a hidden bunker accessible only by breaking through a weak floor in Cave C. It contains the Golden Mask cosmetic and extra lore.
- Night Vision vs Flashlight: Night Vision uses batteries but doesn't attract enemies. Flashlight draws cannibal attention. For stealth in the final lab, use Night Vision.
- Multiple playthroughs: Endings A and C each unlock unique cosmetic items for future playthroughs (save file bound). Ending A gives a pilot outfit; Ending C gives a security guard uniform.
