SPOILER: Main portion of end credits goes over two additional corpses thrown into the collective grave.
After main portion of end credits each member of the band is introduced separately with a full name and a shot of them as a prison guard.
There is a message after end credits in German: "Viellicht ist es so, dass nicht tot zu kriegen ist, was noch nicht richtig celebt hat!" (Maybe it's the case that you can't kill what hasn't really celebrated yet!).
Credits are in a mixture of English and German.
After the end credits there is a scene of band in concert after a brief countdown.
