Airlock Grotto walkthrough

The Airlock Grotto is the Mortuga Submarine's exterior-facing maintenance chamber—colorful, humid, and narratively tied to Godrik Gripp hull work and Madam Tadpole wellness routines. Into Indie Games' July 16 submarine part-two guide ends here after the full early crew roster is met, making the grotto a natural checkpoint before mid-campaign suspicion escalation. This walkthrough documents verified launch-week steps: switchboard power requirement, blue magnetic needle recovery for Captain's Cabin pinboard, and Tadpole's introduction scene.

접근 요건

• switchboard plugs 완료 — Control Room 배선이 끝날 때까지 외부 maintenance 조명 offline.
• Bunk Rooms sweep과 optional Dream Chamber 후 방문 — piggy bank puzzle 급여 clue가 Tadpole 대화 맥락화.
• 초기 grotto inspection pass 완료 후 다른 잠수함 방과 같이 map fast travel 예상.

Grotto 조사 경로

1. Maintenance pouch: 파란 compass needle(315° 각인) 수집 — 다른 deck의 red·silver·gold needle과 함께 후반 pinboard solution에 필요.
2. Buoy marker: grotto float를 town square fish market 일정과 비교 — Zephyr weather cross-examination에 공급.
3. Gripp optional tour: 전원 후 spawn된 Godrik maintenance 대화 트리거; 모든 용의자 tier-two suspicion이면 Pressing Matters flavor에 기여.
4. Madam Tadpole reveal: 마지막 early-game crew 소개 — grotto intro animation 후 formal interview 시작; generic wellness 질문 전 piggy bank payroll slip 제시.

Completing the grotto sweep marks the end of verified community “part two” submarine routes as of July 18, 2026—later chapter ordering and finale reconstruction remain undocumented in public walkthroughs we trust.
