In the XXII century, mankind has colonized the Solar System, and there are habitable colonies on the Moon, on Mars, and at the largest satellites of gas giants. It's time to conquer the constellation of Cassiopeia. Several expeditions are heading there, and each player leads one of them. In Cassiopeia, you have the best specialists at your service: from programmers and cybernetists to smugglers and pirates. With their help, you will be deploying satellites over the planets, building enormous complexes, and sending your cruises and barges to flight — and you will be doing all that to be the first to terraform seven planets and pave the path to a brighter future of the galaxy! All cards are double-sided and during the game, they are all placed on the table and visible to everyone. The players flip the cards over to resolve their various effects and to terraform their own planets.
