The 13th Passenger expansion for Lifeform is a modular, plug-in expansion for hardcore players who want even more! There are four optional modules: Two new characters join the Crew team. New rules for asteroids add yet another terrifying threat to the already beleaguered Valley Forge starship. The Remora shuttle board provides a brand new and unique endgame showdown experience. And the new Crisis cards enable a lone player to use the Remora, and expand the solo experience. This expansion was originally available as an add-on during the Kickstarter campaign for Lifeform.
