Seastalker

About

Seastalker is a text-based adventure game where you play a young marine scientist racing to an undersea research lab under siege. Infocom’s 1984 title drops you in an untested submarine with a robot helper named Tip, navigating you toward a facility attacked by a sea creature, and possibly sabotaged by a human. Every decision matters as you solve mechanical failures, avoid deadly marine life, and piece together clues about who’s meddling with the Aquadome’s systems. The game leans into classic interactive fiction puzzles, requiring careful inventory management and logic to survive the ocean’s depths. The dual mysteries of the saboteur and monster create a tense, layered story that feels ahead of its time. Though aimed at younger audiences, the clever environmental puzzles and atmospheric descriptions drew praise from older fans of the genre. With roots in the same team that later made Moonmist, Seastalker stands as a lesser-known but solid entry in Infocom’s library. Its blend of science and suspense remains engaging for players who enjoy figuring out stories through text.

Storyline

The player's character is a young inventor and marine scientist. A research facility called the Aquadome issues a call for help, indicating that the undersea structure is being attacked by a sea monster. 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.
