This has happened twice now both in mid 20 sounds stopped for zombies and stopped getting drops. Tried to make drop in bank but won't even let u create a power up :/ anyone else had this problem I think it might be a bug! Sort ya shit out treyarch!!!!
the drops get less and less at higher rds. at mid thirties and up 4 player they basically stop.
This wasn't because of high rounds they just stopped dead then it wouldn't let me even create a money drop in the bank. I've been to round 56 before so I know how the drops get less the higher rounds you get
What console are you on? I'm on xbox and have not experienced that problem.
Xbox 360 I had seen another thread about the same problem was weird because they said the zombies stopped making noises too
