I've been trying to get this trophy with 4 players in co op local play but it seems you don't hear the voices.
My questions are:
-Can i still get this trophy this way even without hearing anyone?
-Is there another way you can do it 4 players coop from the same ps3?
-Is there a way you can log in on 1 ps3 with different ps accounts at the same time?
-If all this doesn't work, is anyone interested in doing this with me?(accountname: kennedylaan)
