Stationfall is an interactive fiction computer game written by Steve Meretzky and released by Infocom in 1987. Like the majority of Infocom's works, it was released simultaneously for several popular computer platforms of the time, such as the Commodore 64, Apple II, and PC. The game is a sequel to Planetfall, one of Infocom's most popular titles. It is Infocom's twenty-fifth game.
Following the events on Resida in Planetfall, the player's character received a promotion from lowly Ensign Seventh Class to Lieutenant First Class. The life of an officer in the Stellar Patrol is no better than that of a humble enlistee, however. Five years after the thrills of saving an entire planet from destruction, the character is stuck in a boring desk job that demands piles of tedious paperwork instead of menial cleaning duties.
A typically boring assignment comes in: accompany a spacetruck to a space station and pick up a load of "Request for Stellar Patrol Issue Regulation Black Form Binders Request Form Forms". To make things even more dull, spacetrucks are fully automated, so it will pilot itself once the proper coordinates are entered.
But the task does authorize the use of a robot assistant, and coincidentally enough, Floyd, a beloved companion revived at the end of Planetfall, is one of the choices.
Once the player and Floyd reach the space station, they find it largely deserted. There are two living things on board: an ostrich and an Arcturian balloon creature, both apparently in perfect health. There are plenty of automated devices. It is unclear where the people have gone. The mechanical hull welders also seem intent on inflicting serious harm, which is unusual behavior.
Exploring the deserted complex, there are initially few clues. The station's missing commander audio log can be found, but it provides no solid answers. A ship of unfamiliar design is docked, empty except for alien skeletons and a strange pedestal that looks like it should hold something but stands empty.
Floyd finds two fellow robots: an intellectual model named Plato and a not-yet-conscious "baby" named Oliver. Plato accompanies Floyd and the player, although his personality slowly changes from mild to sullen to aggressive. It is slowly revealed that every machine still functioning on the space station is hostile towards humans: besides the actively homicidal tendencies of the hull welders, the food dispensers manufacture poisonous food and drinks, and even seemingly harmless devices will explode unless powered down. Before long, Plato attempts to kill the player; Floyd is conflicted between the two friendships but reluctantly destroys the other robot. He moves from sadness over Plato's death to belligerence before disappearing altogether.
A pyramid-shaped artifact is emitting some sort of energy, the player discovers, and this energy causes anything mechanical to rebel against humans. All the people on the space station were killed by the machines. Whatever the pyramid is, the machines are building countless replicas of it that will be sent to "infect" other installations and similarly take them over. Before the player can put a stop to this, however, Floyd reappears, completely under the evil influence of the pyramid. In order to survive, the player has no choice but to kill Floyd. This time, however, the damage is too severe and there is no chance of repair for the robot. After the pyramid is defeated, Oliver finally comes to life, and seems almost to be a reincarnation of the once-childlike and playful Floyd.
