Why won't my PS3 find any matches for NAZI ZOMBIES on my PS3?

May be...

Whenever i click find game for Nazi Zombies on Nacht der Utoten it searches but it never finds a game. i beat the regular campaign mode but it not working still. i'm right now playing veteran mode to get the trophies but Nazi Zombies doesn't find a game. does anyone know why this happens???

nacht der untonten takes ages to find someone.

do the other nazi zombies or else you'll have to wait

Alot of people are playing on the map packs now.

Because no one else is playing ?

because everyone is playing on a 360, either that or it is lagging very bad
