Dungeon Explorer is based off of Gauntlet, but adds a plot, bosses, magic spells and RPG elements. Notably, it also one-ups Gauntlet by allowing for five players, embarking on a quest to retrieve the Ora Stone for the King of Oddesia, who is then revealed to actually be Natas, an evil alien king. They then chase him down and ultimately defeat him, taking the stone back.

...At least that's what normally happens. Here, Darkman425 decides to take the throne of Oddesia by using a debug in-game code, allowing to walk through collision, including in front of the throne after Natas steals the stone.
