Regina — Ibis Island Infiltration

This guide covers Regina's full infiltration of the Ibis Island research facility, from restoring power in the outer yard to escaping the island after the Third Energy incident.

Difficulty:

(Hard / Strict Ammo & Item Box Management)

Key Points

Playable Character: Regina, S.O.R.T. operative on a stealth extraction mission
Core Mechanic: DDK cipher discs and colored lever/panel puzzles gate nearly every door
Key Threats: Velociraptor packs, Pteranodons, Therizinosaurus, and the T-Rex
Save System: EPS Card-based saves at fixed terminals — no unlimited saving

Recommendations

Keep the PA-3 Shotgun loaded and prioritize it over the handgun against raptor packs — it staggers them before they can lunge.
Deposit spare ammo and unused keys in the Item Box rather than carrying everything — inventory space is extremely limited.
Read every memo and guard log immediately: safe codes and lever sequences are often buried in flavor text.
Save at every EPS terminal you pass — encounters with the T-Rex can end a run instantly.
