There is no denying that Bloodborne has been a great success selling more than 2 million units worldwide. That is no small feat considering it's a new IP but Bloodborne does have a very passionate community, so this announcement should be met with much excitement.
At the Tokyo Game Show 2015 Sony and From Software announced an expansion called Bloodborne: The Old Hunters, which expands on the story elements from the main game.
Here’s a bit more on the story from PlayStation Blog:
Set in a nightmare world where hunters from the past are trapped forever, explore brand new stages full of dangers, rewards, and deadly beasts to overcome. You’ll find multiple new outfits and weapons to add to your arsenal as well as additional magic to wield and add more variety to your combat strategy.
With new story details, learn the tale of hunters who once made Yharnam their hunting grounds, meet new NPCs, and discover another side of the history and world of Bloodborne.
The Old Hunters launches on November 24th for $19.99
