Game description from the publisher:
Humans!!! 3: ZombieCon moves the brain-munching action to the happiest place on earth. That's right – your zombies have decided to look for lunch at the local gaming convention. Will you eat the CCG player? Maybe the RPG fan would be easier to catch. If all else fails, security looks tasty! So many choices!
Humans!!! 3: ZombieCon lets players explore a large gaming convention looking for more brains to eat or candidates to convert. This expansion also adds a new card type called "Personalities" that determine WHO you encounter and how much "fight" they have in them.
