''Mission: Thunderbolt'' is a roguelike computer game with a futuristic storyline. It was originally developed and released on DEC mainframes as ''Doomsday 2000'', a four-part game, and later ported to both Mac OS and Windows. ''Mission: Thunderbolt'' is part 1 of the ''Jaunt Trooper'' series and was released on both Mac OS and Windows. Part 2, ''Mission: Firestorm'', was only released for Mac OS. The game was one of the first commercially released roguelikes. It put a graphical front end and a full set of sounds in place of the ASCII text traditional to roguelikes. It was also unique in the sheer number of actions/interactions possible. Being closed source, many mysteries of the game were never fully resolved. ==Historical background== The creation of this game began in late 1986 as a means for the author to learn the C programming language while working for DEC. The game was developed under the VMS operating system on a DEC VAX mainframe computer; a VAX workstation was used in later years. The first version was released after nearly a year of development and testing to DEC employees worldwide over the Internet in 1987; the author kept a large world map on the wall of his office and had a pushpin placed where ever a DEC office was known to have employees playing the game (there were lots of pins). Although titled ''Doomsday 2000'', within DEC the game was known simply as ''Doom''. ''Doomsday 2000'' was modeled along the lines of other popular mainframe computer games at the time, such as ''Rogue'', ''Hack'', and ''Larn'', but was specifically designed to have much greater depth of game play and greater freedom with regard to interacting with the game world presented; these are aspects that set the game apart from all other mainframe games of that era. For example, you could bash down walls to gain access to otherwise seemingly inaccessible regions. One trick that was often used by players was to blow a hole in the floor above a particularly troublesome foe lurking on a lower level, then lob grenades through that hole to destroy the critter from relative safety, though some foes were clever enough to clamber up after the player character. Another notable feature that was provided, and which may very well have been a first such instance for mainframe games, was the inclusion of special loadable bitmap fonts for various models of DEC's VT series video computer terminals. These fonts enabled the game to present actual little pictures of the monsters, loot items, and terrain features found in the game, instead of the simplistic number/letter representations (ASCII characters) used by other games at that time. So a "bat" was shown with the image of a stylized bat, instead of the letter B. ''Doomsday 2000'' was initially conceived of as a four part-game with interlinked stories, each part being a special "mission" for the heroic character (Captain Hazard) whose role people assumed within the game. ''Mission: Thunderbolt'' was the first of the missions, and it was the only mission in the 1987 release. This initial game was later expanded over time to also include ''Mission: Firestorm'' and ''Mission: Quicksilver''. The fourth mission (''Tsunami'') never left the concept stage. Casady & Greene published a version of the game's first mission as ''Mission: Thunderbolt'' for Mac OS in 1991. Few copies were sold and so was not a commercial success for its author. The second mission was subsequently released by the author himself for Mac OS as ''JauntTrooper, Mission: Firestorm'' by way of a hobby, rather than a commercial venture, as was a Windows version of the first mission, ''JauntTrooper, Mission: Thunderbolt''.
