The new cards in the Santarri Mutant Men Supplement are designed to be shuffled right into the existing COPE card decks and will give your Aliens powerful new Events and Space Stuff. But beware, the National Guard are out in full force to stop you and they have brought along a very well-armed and very ornery redneck as a local guide! This pack was included as a bonus for those who purchased Conquest of Planet Earth: Apocalypse at GenCon and PAX in 2012, but now seems to be exclusively available from the Flying Frog website.
