During the game the players will be able to capture asteroids thanks to their launch bases, located on the asteroid belt. The asteroid thus acquired will create a personalised effect track, which will give each player unique bonuses. However, the asteroids could also crash into planets in the solar system, modifying the status of the deposits in the planetary zones or even the resources that can be extracted from the sun.

In Starship Interstellar each player takes the role of a powerful corporation, and all of them are “cooperating” to save humanity from the disaster they themselves caused: they have to build the Starship Interstellar, hibernate in it the more people they can, and find a route to an inhabitable planet.
