Frederik Pohl's Gateway is a 1992 interactive fiction video game released by Legend Entertainment, and written by Glen Dahlgren and Mike Verdu.
It arrives at a huge space station carved out of an asteroid floating halfway between Venus and Mercury, which is full of thousands of similar ships, but otherwise empty.
Although they were unable to reverse engineer the Heechee technology, they can use the ships' stored destinations and the station becomes humanity's "Gateway" to outer space, hence the name.
Leonard Worden, the deputy chief of the exploration program, informs the player that even after all those years, reactivation of the Heechee technology by humans would only make them detectable to the Assassins.
The game plot then sends the player to four planets in order to activate a shield device that would 'cloak' the technology signal from the Assassins.
The similarities soon end as the game introduces original elements, changes (in the novel's terms: travel times are negligible, Gateway has Earth-normal gravity, all ships are ones and bastard control panels are the norm) and material from the later books.
Computer Gaming World's Charles Ardai stated that "Pohl's influence is felt throughout" Gateway except in the puzzles, which were "pretty good" but based on "the last decade of adventure game design ... most would not be out of place in a golden oldie like Starcross or Planetfall", especially the "jarring and inappropriate" logic puzzles.
He concluded that for those "looking for weeks of game play and puzzle solving it may seem a disappointment, but for an entertaining story it hits the spot.
