Dark Castle
Dark Castle is a computer game trilogy. The first game, Dark Castle, was released for the Macintosh in 1986, by Silicon Beach Software. Similar to Prince of Persia, it is an action/adventure game where a young hero named Duncan tries to make his way to the evil Black Knight, solving puzzles and gaining objects and spells on the way. Unlike most other games, the player has no impressive weapons but has to throw rocks at his enemies. On occasion, there are weapons such as shovels which can be picked up but only used within that screen.
In 1987, the sequel Beyond Dark Castle was released, in which Duncan has to return and defeat the Black Knight who is still alive. To access the Black Knight's tower, the player must first gather five magic orbs which are placed in various hard to reach places. Beyond Dark Castle had an engine similar to Dark Castle but with improvements and additions, including some levels where the player could control a "mediaeval jetpack" of sorts. Playing the game on the "Advanced" difficulty level allows the player to see an extended ending cinematic which reveals that the hero Bryant actually puts on the defeated Black Knight's helmet and armor, becoming the new evil ruler himself.
In 1994, the gaming company Delta Tao acquired the rights to some of Silicon Beach's old games, via Aldus, and were able to produce and publish a modernized color version of the original game. In 2000, a new sequel called Return to Dark Castle was announced, where a new young hero called Bryant must once again defeat the Black Knight. It is still in development.
