Citadel of the Black Sun

Citadel of the Black Sun is a fantasy adventure built around exploration, danger, and the ominous business of investigating a mysterious stronghold. The game places the player in a world of hostile creatures, hidden passages, puzzles, and treasures, rewarding curiosity while making careless exploration rather hazardous. Its old-school design expects players to remember locations, experiment with objects, and pay attention to clues rather than relying on modern conveniences such as helpful glowing arrows. The atmosphere is one of its strongest qualities, with the titular citadel providing a suitably sinister destination for the adventure. Combat and exploration work together to create a steady sense of uncertainty, since the next room may contain either something useful or something extremely interested in shortening your life expectancy. It is a modest but atmospheric slice of classic computer fantasy.
