Habitation Ring — Walkthrough
Open hub area. Two parallel objectives — lab side first, then power core. Optional Silent Array fight gives you the Stagger Cannon a chapter early.
Objectives in order
- Find REM 'Diana-Sigma' near the locked lab door.
- Solve Puzzle 2-1 to unlock Diana's old lab.
- Solve Puzzle 2-3 for Hacking Module I (improves every later puzzle).
- OPTIONAL: Beat Silent Array for the early Stagger Cannon.
- Defeat Warden-X.
Tips
- Run the Silent Array detour. The Stagger Cannon trivialises Monolith Engine in Ch.3.
- Buy HP Upgrade I before Warden-X — he two-shots you otherwise.
Boss fight
The chapter ends with Warden-X. Weak point: Back vents during overheat. Drops: Lunafilament ×4, REM Data: "Diana-Sigma", Hacking Module II.
