Key & Compass presents:
Submarine Sabotage
by Garry Francis

Submarine Sabotage is a Z-machine interactive fiction game written with Inform 6 and is © 2023 by Garry Francis. It was an entry in PunyJam #3 where it won 1st place.

In this game, you play as Seaman Recruit Williams of the USS Ibis, a US Navy submarine submerged near Alaska. Spotting some unknown whitish gas, you quickly dive into the airlock and close the hatch behind you. Now what do you do?

This solution is by David Welbourn, and is based on Release 2 of the game.

SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.
