This game is a version of Rogue 5.4. It was originally developed by Michael Toy, Ken Arnold, and Glenn Wichman from 1983 to 1985. This was the last version created for Unix.
The Roguelike Restoration Project updated Rogue 5.4 to run on modern systems.
The Roguelike Gallery's version has been further modified to work with dgamelaunch and to log the results of all games.
