Ahh so it's a fairly recent fault... well.. either it gets fixed in the next few days or I'll be asking for a full refund. We haven't had any time on it whatsoever.
It's unnaceptable paying full price for this game and finding out the co op is broke...its the only reason we got it.
If it was brought on steam I think you can get a full refund within a certain amount of time but not on PlayStation and yea can confirm party chat and all other PlayStation stuff is working fine. It's just this games compatibility with it somehow. Have the studio got a proper contact form for this sort of thing?
