Caelum is a prototype!
Please note that Caelum is not in a finished state, and may still change significantly in the future. You can receive updates of changes with Twitter, Facebook or .

Caelum is a 2D top-down spaceship sim, where you build your own custom spaceship and fly it around the stars. Build whatever ship you want, and control it however you want. Test your skills by building ships to complete a specific mission, including hauling a large awkward chunk of structure to a destination, or hunting down a dastardly enemy spaceship.


You can play Caelum right now in your browser (flash required):
