Instead of exclusive content, Sony’s Adam Boyes announced that Far Cry 4 on PlayStation 3 and PlayStation 4 would allow you to invite your friends to the game, even if they don’t own the game.
The PlayStation Twitter account explained:
Nice detail: Pick up Far Cry 4 on your PS4 or PS3, invite any of your PSN friends to your world…even if they don’t own the game.
