got FarCry4 the other night and when I opened the case they have given me two serial numbers for Keys to Kyrat play co-op mode with upto 10 friends who don't own the game type code in redeem codes in ps store 4hm4-6pn2-lk7j if any ps4 want to give it a try. first come first served I guess. if you need friend to play just send me lifereaper333 a friend request if it helps.
just unlocked the co-op bit .. didn't realise I had to play the online part for a little while to unlock it :/ still its done now best game I've played on ps4 as of yet, nice graphics, runs nice and fun to play.
