You are the director of an Observatory. With your telescopes aimed at the stars, planets, and nebulas of the Oniverse, you're ready to launch daring spaceships into the skies.

Stellarion, the seventh title in the Oniverse series, is a deck-management game. All the cards you will need are split into eight decks, and you know the contents of each one. You will need to manage all these resources to ensure that you have the right cards available at the right time.
