Dark Castle - Beyond Dark Castle

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. The orbs have to be returned to the Ante Chamber and placed on 5 pedestals for the gate to open so Duncan can face the Black Knight.

Beyond Dark Castle had an engine similar to Dark Castle but with improvements and additions, like a health bar, bombs, and other items, also including some levels where the player could control a "personal helicopter" of sorts. These levels and maze levels were side-scrollers instead of being limited to a single screen. Games could also be saved in a "computer room" level. Like all versions of Dark Castle, if the player beats the game on advanced, it will give a special ending.
