Chronomaster is a computer DOS-based adventure game developed by DreamForge Entertainment and published by IntraCorp in 20 December, 1995. Its main plot was written by novelist Roger Zelazny and was his last known work, as he died during the development of the game.

Chronomaster narrates the story of Rene Korda (voiced by Ron Perlman), a retired and formerly renown designer of "pocket universes" — self-contained worlds developed according to the tastes of the person who finances their construction. Korda is hired by a representative of the "Terran Regional government" to remove two pocket worlds from a state of "temporal stasis" and to find out who is responsible for the situation.

To be able to move within pocket universes in which time is stagnant, Korda employs "bottled time", a container which when opened provides him with a field in which times flows as normal. Bottled time may also be used to activate objects and trigger ongoing events which were halted by the temporal stasis. He also counts with the help of a versatile context-sensitive tool which makes available different functions to him, depending on the pocket world he visits. During his journey Korda is accompanied by his personal assistant Jester (voiced by Lolita Davidovich) and eventually by Milo, a refugee (voiced by Brent Spiner).
