Ground Zero may be placed on any bunny in The Bunny Circle forcing the next weapon revealed by any player to be used on the targeted bunny. The player who reveals the next weapon must have a bunny in The Bunny Circle to launch the weapon. Ground Zero remains in play until a weapon targets the bunny. If the player who owns the bunny counteracts, eliminates or defends (using Defense Cards) against the weapon, then Ground Zero is still removed (discarded) regardless of the outcome of the weapon launch.
