Dungeon Master is a role-playing video game featuring a pseudo-3D first-person perspective. It was developed and published by FTL Games for the Atari ST in 1987, almost identical Amiga and PC (DOS) ports following in 1988 and 1992. Dungeon Master sold 40,000 copies in its year of release alone, and went on to become the ST's best-selling game of all time. The game became the prototype for the genre of the 3D dungeon crawlers with notable clones like Eye of the Beholder. Gameplay In contrast to the traditional turn-based approach that was, in 1987, most common, Dungeon Master added real-time combat elements (akin to Active Time Battle). Other factors in immersion were the use of sound effects to indicate when a creature was nearby, and (primitive) dynamic lighting. Abstract Dungeons and Dragons style experience points and levels were eschewed in favor of a system where the characters' skills were improved directly via using them. Dungeon Master was not the first game to introduce these features. Dungeons of Daggorath for the TRS-80 Color Computer first employed them in 1982. Dungeon Master was, however, responsible for popularizing these elements. Other features of Dungeon Master included allowing players to directly manipulate objects and the environment by clicking the mouse in the enlarged first-person view. It also introduced some novel control methods including the spell casting system, which involved learning sequences of runes which represented the form and function of a spell's effect. For example, a fireball spell was created by mixing the fire symbol with the wing symbol. While many previous games such as Alternate Reality: The Dungeon, The Bard's Tale, Ultima, and Wizardry offered Dungeons & Dragons-style role-playing, Dungeon Master established several new standards for role-playing video games and first-person video games in general, such as the paper doll interface. As Theron, the player cannot progress past the first section of the game until they have selected at least one and up to four champions from a small dungeon containing 24 mirrors, each containing a frozen champion. The frozen champions are based upon a variety of fantasy archetypes to allow diversity within the player's party. Plot Many champions have been sent into the dungeon with the quest to recover Librasulus' (the Grey Lord) firestaff. With the firestaff, Librasulus can take physical form again and defeat Lord Chaos. The player is Theron, the apprentice of the Grey Lord, that goes into the dungeon
