Disc Error !!!

The sound skips, eternal Ladzeiten and already in the prologue, the first Bugs that the zombie neighbor is "slipped" through the door. In the car were suddenly both front men, etc., etc.
More than 20 minutes, I could not look at the chaos.

Annoyed to the dealer (the big red MM) and exchanged and there, suddenly everything runs smoothly, no long loading times etc.

So in my opinion the fault lies on some discs that are nascheinend faulty.
Similar experiences have also already made a who has only awarded 1 star.
In other forums can be read like that.

Too bad fo the first frustration, because otherwise the game is awesome!
