Design Materials is the name given to the second set of cards obtainable only during the second playthrough of No More Heroes. Each card features different types of concept art from the game, including character designs, expressions, weapons, profile cards, and art of several other things surrounding the game, including Pure White Lover Bizarre Jelly.
As for uncovering these buried trading cards during the second playthrough, if the player has purchased the Accelerator from Naomi's Lab, when in the vicinity of buried treasure the Wii Remote will make a slight vibration. If the player progresses in the right direction towards the buried treasure's location, the Wii Remote will continue to make brief vibrations. If the player progresses in the wrong direction towards the buried treasure, the Wii Remote will no longer make these vibrations. As the player progresses closer to the buried treasure, the vibrations will intensify, and when the player is standing over, or extremely close to the treasure, the Wii Remote will make constant, intense vibrations. If the player has not obtained the Accelerator, this can be a difficult process of trial and error.
- Design Materials contains one hundred cards.
