Death Cards

 Death Cards are playing cards found throughout Call of Duty: World at War. They are attached to helmets and placed on top of vertical rifles, and are often found near fallen enemies who have not been killed during the level. Death Cards are similar to Call of Duty 4: Modern Warfare's and Call of Duty: Modern Warfare 2s Intelligence pieces. They each unlock a special ability in co-op play. They can only be used in private matches.

Trivia

 * There are no Death Cards on the Wii version.
 * There is no card with the number seven, instead there is a joker.
 * It may be possible that the idea of Death Cards came from the movie Apocalypse Now, when Lieutenant Colonel Kilgore took out a deck of cards with the same image on the back on the cards and threw a card on each of the bodies (probably to identify them).
 * Near every Death card there is a dead enemy right beside it, it is possible that the weapon that is beneath the death card is theirs. The level Vendetta is the only exception, where the corpse is of a Soviet soldier instead.
 * Death Cards were originally able to be used in Nazi Zombie Private Matches due to a glitch. However, it was later patched.
 * The death cards rest upon the standard issue rifle of the campaign's enemy. So the Arisaka in the American and the Kar98k in the Soviet campaign.
 * If you look close at the rifle focus on the trigger and look down you will see a dogtag with the Treyarch logo.
 * Death Cards are very similar to the skulls in the Halo series of video games, considered by some as competition for Call of Duty for the Xbox 360. In fact, the effects of many Death Cards are similar if not the same as skulls in Halo 3.
