This is a re-release of Marooned to be compatible with Arcane Dimensions. The majority of changes between this version and the Mjolnir version are adjustments to monsters, weapons and items. Only small tweaks have been made to the actual map, it remains largely the same. This re-release is intended to reach a wider audience that may have skipped it due to its Mjolnir exclusivity, or prefer the Arcane Dimensions mod.
Marooned is designed to be played with an engine that supports skyrooms, such as Quakespasm Spiked or FTE. Other engines like Ironwail and VKQuake are fully compatible, but you will not see the various ships/meteors/UFO's flying in the background, it will only display the standard skybox.
