There are two cards available for each combination-weapon available in Dead Rising 2: an inferior Scratch Cards and a superior Combo Card. The Scratch Card is given when you make a combo weapon by accidentally combining two items. You can find the appropriate Combo Card throughout the game, when found the Scratch Card will be replaced with a Combo Card.Both cards indicate the two weapons required to build the combo weapon. Possessing the Scratch Card grants the player a PP bonus when using that weapon but does not allow the player to employ that weapon's secondary attack. Players obtain a weapon's Scratch Card by combining two eligible weapons into a combo weapon at a workbench or by buying that weapon from a pawnshop.
- It is impossible to get a Scratch Card for the Spiked Bat, because it will automatically grant a Combo Card when first made unless you join someone elses co-op game who has already unlocked the Maintenance rooms before you have. This will enable you to make Spiked Bats with a scratch card.
- It is impossible to get a Scratch Card for the Wingman, as the only way to get it is to create it.
