Players use a hand of six hex-shaped cards to build a map of space and planets, and play events that affect the game. As the map is built, players roll and move their spaceships around the galaxy, collecting data which is then used to upload hex cards to their "mission files". The first player to complete his/her Mission File wins the game. This is a light game with complexity that comes from the possible interactions between the hex cards. There are elements similar to Magic the Gathering in this game, on top of similarities to other map building games.
