Bloodborne has a feature named “Chalice Dungeon”. This is a dungeon that is opened up by performing rituals in the game’s hub central hub, and is different depending on the combination of items you use in your ritual.
For this reason, no two players will spawn identical dungeons, and players will be able to invite others into the Chalice Dungeon of their copy of Bloodborne. The size and difficulty of each dungeon will vary, as will the enemies and boss fights within.
You can see From Software demonstrate the Chalice Dungeon feature in the video above. Bloodborne will launch on PS4 this March in the U.S. and Europe.
