The only way you can use death cards is on co-op mode but it has to be private, have four people join a co-op party, change the setting to how you want them, and in the menu somehwere you will find cheats, then the host can chose what cheats to have on or off, it is better for the person with the most death cards to be host because they can turn on more cheats than other players in the party.
What you do is go onto a private match, go on settings, select phrase at bottom turn cheats enabled to yes and click on each death card for which one you want
If you mean the death card? Then go on the misson 'heart of the reich'. As you begin, head up the stairs you start on, turn left, head across the street to the stairs on the opposite side. The death card is at the bottom of the stairs. It unlocks the paintball gun cheat for online play.
On the level Heart of what ever go straight up your @$$ turn left go over to the other side of the street in a subway station entrance in the corner next to the dead body!
