In XYbrid, players use transparent cards to build monsters in a diabolical quest for infamy. Exploit biology, robotics, physics and chemistry to assemble myriad abominations—XYbrid parts combine in over half a billion ways. Players build monsters over 3 rounds by drafting parts (arms, legs, heads, etc.) from a shared pool called the Lab. Mission effects raise the stakes each round, and Breakthrough cards reveal surprises that can dramatically shift the game. The most infamous player after 3 rounds wins.
