The Ark was abandoned by the Shee because a meteor hit the ship, but the infrastructure still remains in working order.

There are 6 main "metarooms" on the ship; the Norn Terrarium, Grendel Jungle, Ettin Desert, Marine area, Bridge, and Engineering Room.

The Engineering Room is where the Agent Creator is, with which you can create objects for your world.

Creatures 3 runs on the CAOS engine, making it highly moddable, but now it is retired and outdated.

In December 2021, Creatures 3 was released on the Steam games service.
