You are a crew member in an alien ship. Alien for humans of course. The ship is malfunctioning and you are stranded in the human solar system. Using primitive detectors, you are trying to identify as many planets as possible. The quest is finished when Earth has been claimed and no one disproved the claim after 2 rounds or when a crew member receives maximum influence from their captain. The winner is the crew member with the most influence. Each player holds a detector card and a bunch of colored tokens. Each round players execute 2 actions each turn. The possible actions are: Detect, Claim and Disprove. Detecting Players use the detector cards and place them under each hidden planet. Once flipped the player secretly sees a part of the planet and notes down the information. Claiming Players move the claimed card from the game board onto it's claimed location. Disproving Players use their detector card to disprove an existing claim.
