In Dead Rising 2 for the PS3, Xbox 360, and PC, there is one secret combo card that you receive simply by creating the combo weapon.
Check out my other guide if you’re looking for the full list of combo card locations.
Wingman (Queen + Nectar) – This combo card is given to you by simply creating this combo weapon. Queens come out of zombies that are flailing about grabbing at their necks, and nectar is created from combining two orange juices in a blender. To attract a queen, simply use a nectar and one should come. It looks like a small bug when it’s outside of a zombie.
