I just got the game for the ps3 a few days ago and i was wondering how i get to the zombie mode, and is it only an online game or is it offline too.
To unlock Zombie Mode (More known as Nazi Zombies or “Nacht Der Untoten”) you must complete the Campaign on any difficulty. You can then play Nazi Zombies either online or offline.
To play it online, select “Co-Operative” on the Main Menu. You then go to Settings and change the Game Mode to “Nacht Der Untoten”. Then you can either go “Find Game” to join a Match with other players, or select “Private Match”. To play online with other players on Private Match you must invite people for them to be able to join.
To play it offline, select “Solo” on the Main Menu. Then go to “Mission Select” and at the bottom of the list you should find “Nacht Der Untoten”. Select that and then you will see a short cutscene introducing the Nazi Zombies Mission and then you will start.
Hope I Helped.
