PSN players don't have to own Far Cry 4 to play
Language »
Players who own Far Cry 4 will get to invite their PSN friends to multiplayer matches even if they don't have a copy.
Ubisoft announced the PlayStation exclusive feature during Sony's press conference last night, and it applies to PS3 and PS4 versions.
The co-op mode begins dynamically when a friend joins your game, but when they join all solo missions are turned off and you're left with the open-world.
Check out a video of co-op play in action below.
