Can you complete nazi zombie mode on cod5 if you can What is the last level

yes you can because get the last zombie map and read it in each map there are secret messeges and the last map says the last words then you have to go to last map (der reiese) and click on all the boxes that have a lightning bolt on them (click x on them) then then you will get a key board type in the messege and the pack a punch turns into a rocked the door goes back up and you escape and after it plays u video explaining the zombies its veryy cool

well enjoy
