Using the same graphical interface as Deja Vu, Shadowgate is an adventure game set in a fantasy world. Players take the part of an adventurer sent to the ancient keep of Shadowgate on a quest to find a mystic artifact known as the Staff of Ages and stop the evil Warlock Lord from summoning a horrific demon known as the Behemoth. However Shadowgate has become infested with the Warlock Lord's demonic minions, not to mention the castle's still functional booby-traps.
