A new Bloodborne trailer released by Sony has explained the game's new procedurally-generated 'Chalice Dungeons'.
Presented by producer Masaaki Yamagiwa, the video goes into further details about the Chalice Dungeons and Messenger Creatures, which behave in a similar way to the Souls series' Soul Signs which allowed players to leave messages for other people.
"The Chalice Dungeons are underground ruins found beneath the city of Yharnam." Yamagiwa says. "It's a vast area with many different levels and layers. The concept we had is that they change depending whoever is looking at them, rather like procedurally generated maps."
Bloodborne launches exclusively on PS4 on March 27.
