Rogue (video game) Rogue (also known as Rogue: Exploring the Dungeons of Doom) is a dungeon crawling video game by Michael Toy and Glenn Wichman and later contributions by Ken Arnold. "Rogue" was originally developed around 1980 for Unix-based mainframe systems as a freely-distributed executable (Public domain software). It was later included in the official Berkeley Software Distribution 4.2 operating system (4.2BSD). Commercial ports of the game for a range of personal computers were made by Toy, Wichman, and Jon Lane under the company A.I. Design and financially supported by the Epyx software publishers. Additional ports to modern systems have been made since by other parties using the game's now-open source code.
