There are two cards available for each combination-weapon available in Dead Rising 2: an inferior Scratch Card and a superior Combo Card. Both cards indicate the two weapons required to build the combo weapon. Possessing the Combo Card grants the player a PP bonus when using that weapon and also allows the player to employ that weapon's secondary attack. Unlike Scratch Cards, which are only obtained by combining eligible weapons into a Combo Weapon (or buying items from a pawnshop), Combo Cards can be earned through a variety of ways:
- By learning about a possible combination by examining items and posters throughout the environment.
- From leveling up.
- By defeating certain Psychopaths.
- By rescuing certain Survivors.
