Chase Across the Planes is a boardgame for two to four players set in the worlds of the Intruder. The game was published in Intruder magazine #1. Player assume the roles of supernatural characters who are testing their powers for the first time... each character has a special ability that allows them to 'bend' the rules in a slightly different way. Players move around a small stylized mapboard that represents the different planes of existance, attempting to visit each one and 'leave their mark'. Along the way, they may battle other characters and/or destroy other player's markers. As soon as a player has markers in all of the planes required (depending on the number of players, this can be 4 to 6), he wins.
