Are you a fan of SCE Worldwide Studios President Shuhei Yoshida's positive attitude and smiling approach? Let's see if you find his Chalice Dungeons in Bloodborne as pleasant.The popular executive shared on Twitter the codes for two of his procedurally-generated labyrinths, which means that now you can play them too.

All you have to do is to search via Chalice Glyph and insert "gqgtq23r" for the easier Pthumerian Labyrinth, or "4dy5v9m2" for the more challenging Central Pthumerian Labyrinth, and you'll be able to partake in Shu's blood feast.

Both dungeons are actually very fun to run, and the second can be definitely challenging if you're not familiar with the game's difficulty yet. The loot is, of course, proportional to the challenge.

If you want to see the dungeons before you run them, you can find screenshots aplenty below. Beware, though, as they obviously include spoilers of what enemies and bosses you'll encounter.
