From Software is planning to release a new patch for PlayStation 4's Bloodborne next week, which tinkers with cooperative play.
The plan is to make sure that all players who are summoned by friends into passworded co-op games are playing at the same level. Currently, only players on a similar level can play together. A blog post on the PlayStation's Japanese website states that Update 1.05 will ensure that all guests will have their level modified to match that of the host's.
