Keys to Kyrat
PlayStation gamers will be able to invite their friends for a round of cooperative play in Far Cry 4 even if said friends do not own the game. We've known about this for a while, but more specifics have come out of the PlayStation gamescom 2014 press conference.
Far Cry 4 owners will get 10 "Keys to Kyrat," which can be sent to other players for up to two hours of co-op play in the game's open world. Explore, capture outposts, and murder animals together.
