A new Cosmic Age is dawning and with it arrives a new cast of extraterrestrial beings struggling for complete galactic domination! Cosmic Incursion brings 20 additional races to the Cosmic Encounter core set and marks the return of 10 classic Cosmic Encounter aliens. Cosmic Incursion also expands the universe with added components for a 6th player, and introduces a new variant to spice up gameplay - the reward deck, which offers exciting new cards such as kickers and rifts to those aliens who ally with the defense.
