So I've bought both cod4 and Horizon Zero Dawn in the past on my American psn account.
But now I want to take advantage of the cod4 map pack sale being cheaper on the EU store. I also want to take advantage of the ps plus discount for the horizon dlc. I'm not a member of ps plus on my American account so wouldn't be able to get it cheaper there.
So my question is will the horizon and cod4 dlc if bought on my EU account work with my games bought on my American account? I'll be playing said titles on the EU account. The main games are region free I know that but are they compatible with dlc from another region?
