Overbearing superior Ensign First Class Blather assigns the player to mop decks, not exactly the glorious adventures promised by the recruiters on Gallium.

But a sudden series of explosions aboard the ship sends the player scrambling for an escape pod, which eventually crash-lands on a nearby planet.

Eventually encountering a helpful but childlike robot named Floyd, the player must unravel the mysteries of the single deserted structure on the planet, Resida, and find a way to get back home.

Wandering to other parts of the ship merits demerits from Blather and an ultimately fatal run-in with the Brig unless the player returns to work.

The pod safety netting breaks the player's fall and an escape kit is produced, which proves critical to survival.

By putting together various clues, slowly the player realizes that the nearly uninhabited island is in fact one of the last remaining landmasses on a planet on the verge of destruction.

The inhabitants initiated a planetwide project to place everyone under suspended animation while automated systems of robots and computers worked towards finding a cure.

Meteorites bombard the planet with ferocious intensity, and the project to find a cure for the plague is itself threatened by the failure of the main computer and repair systems.

Early on in the game, the player finds what at first appears to be the only remaining inhabitant of the island: Floyd, a childish yet endearing robot.

Once Floyd realizes that the ProjCon repair robot (aptly named Achilles) is non-functional, and that the Project is close to completion, he performs the ultimate sacrifice and gives his life to retrieve the vital Miniaturization Card from the Bio-lab (the mutants within kill the player if he tries to get it himself).

The adventurer then uses the Miniaturization Booth to access malfunctioning Relay Station #384 and repairs the main computer by removing an offending speck of dust with a laser.

With a biomask and the help of the Laboratory's poison gas system, the player makes it through the Bio-lab but emerges with the mutants on his tail.

The elevator takes the adventurer to a secret room where the survivors of the infection were cryogenically frozen, just as the entire facility staff is reanimated by the antidote discovered by the ProjCon Computer.

Taking more than a few days causes the adventurer to succumb to the infection which apparently has ravaged the facility unless the antidote is obtained at the underground site.

[1] There are differences in this enhanced remake: the game recognizes verb commands typed in kana (Japanese syllable system) or Latin alphabet.

Also, unlike the original, the remake contains enhanced graphics; every location has a unique background picture, on which the text is super-imposed, like in the PC-9801 version of Zork I and Enchanter.
