With helpful assistant Tip, the player must navigate to the Aquadome in the new untested two-person submarine Scimitar and investigate the problem. But that isn't all... it looks like there may be a saboteur within the Aquadome as well.

Planetfall is a science fiction interactive fiction computer game written by Steve Meretzky, and the eighth title published by Infocom in 1983. Like most Infocom games, thanks to the portable Z-machine, it was released for several platforms simultaneously. The original release included versions for the PC (both as a booter and for DOS) and Apple II. The Atari ST and Commodore 64 versions were released in 1985. A version for CP/M was also released. Although Planetfall was Meretzky's first title, it proved one of his most popular works and a best-seller for Infocom; it was one of five top-selling titles to be re-released in Solid Gold versions including in-game hints. Planetfall utilizes the Z-machine originally developed for the Zork franchise and was added as a bonus to the "Zork Anthology". The word planetfall is a portmanteau of planet and landfall, and occasionally used in science fiction to that effect. The book Planetfall written by Arthur Byron Cover, uses the game image on the cover, and is marketed "In the bestselling tradition of THE HITCHHIKER'S GUIDE TO THE GALAXY.[2] A sequel, Stationfall, was released in 1987.

The year is 2186. Humanity has established colonies on the moon, Mars, and several of the larger asteroids. Earth's sky is dotted with space habitats, and the spaceways are always busy. As usual, there is the urgent need for energy to power this advanced civilization; one of the primary sources of that energy is quantum black holes. In Starcross, you are a miner of black holes, scouring the asteroid belt in your one-man survey ship. Finding and harnessing a single black hole can make a person's fortune. It's a lonely business, fraught with the known and unknown hazards of space. You've equipped your ship, the M.C.S. STARCROSS, with the best gear you could afford. You've put everything into this venture, and though you've tried before, you somehow sense that this time will be different.

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.

You must save the planet above by repairing the Complex you are frozen within. You must do it before they arrive to shut you down. And you must do it not with your own hands, but with those of your robots.
