you cant
you can't
yes
I think on CoD5 you choose Co-Op on either Zombies or Campaign and choose Death Cards.
No, only in co-op campiagn.

No because since there is no Nazi zombies for wii there is no need for the death cards.
Death cards can only be used on multiplayer CO-OP not nazi zombies or single player.
you have to play online with friends that also have those death cards
finding Death Cards unlocks certain "Perks" in online gameplay. Similar to the Halo 3 skulls (If you know what I'm talking about.)
you used to be able to use them but now there has been a patch so you cant use them.
No. There used to be a glitch so they would work, but treyarch patched it so it doesnt work anymore.
I have Flak Jacket and I used to be able to kill zombies w/ grenades, but after i found it couldn't have 2 grenades left to kill a zombie. I say SOME do.
