Dungeons of Daggorath is a 1982 computer game and one of the first games to use a 3D first-person perspective. It was produced by DynaMicro for the Tandy (RadioShack) TRS-80 Color Computer.

The game was written by Douglas J. Morgan and Keith S. Kiyohara, with sounds by Phil Landmeier, in 1980-81. It was released as a ROMpak cartridge for the Color Computer, which limited the size of the code to eight kilobytes, which took several months of recoding to achieve. Despite this, the game features a multi-level maze and has what for the time were advanced sound effects that provide important clues to the locations of monsters.[3]

Despite what are now primitive graphics and sound, the game still enjoys a cult following in the retrogaming community for its challenging gameplay, and has been ported to Microsoft Windows XP and Linux via the SDL graphic and sound libraries.


Dungeons of Daggorath was one of the first games that attempted to portray three-dimensional space, using angled lines to give the illusion of depth. It followed the 1974 games Maze War and Spasim, written for research computers, and the first 3D maze game for home computers, 3D Monster Maze, released in 1981. The game Phantom Slayer, which like Daggorath was released in 1982 for the Color Computer, also featured monsters lurking in a maze. While Daggorath was visually similar to these games, it added several elements of strategy, such as different kinds of monsters, complex mazes, different levels of visibility, and the use of different objects and weapons.[4]

The player moves around a dungeon, issuing commands by means of typing — for example, typing "GET LEFT SHIELD" or "USE RIGHT TORCH" (or abbreviations such as "G L SH" and "U R T"), gathering strength and ever more powerful weapons as the game progresses. Various creatures appear, and can often be heard when they are nearby but not visible. The object of the game is to defeat the second of two wizards, who is on the fifth and last level of the dungeon.


A unique feature of the game is a heartbeat which rises as the player moves and takes actions within the virtual environment. The heartbeat is a direct predecessor of the "health" indicator in later games; the higher the heart rate, the more vulnerable the player is to attack. The player can faint from overexertion, in which case there is the risk of being attacked while defenseless.


After Dungeons of Daggorath became one of the most popular Color Computer games, Tandy produced a sequel, Castle of Tharoggad[5][6], which was made without the participation of the Daggorath team. It did not sell well, and received poor reviews from fans of the original.[7]
