Fundead: The Gravest Show on Earth

Fundead is a two-player strategic card placement battle that pits circus performers against zombies (there is also a 2v2 variant as well as a solo mode). A player can lay a new card to flip existing cards from their opponents' side to their own, and when the five-by-five battlefield is filled with cards, the side with the stronger army is the winner. Cards can also be locked into place and blocked from the opponent's reach.
