Yes according to impressions, there are mobs more in number than few in Souls series.Man, looks like there will be lots of mobile mobs in the city. This is definitely not like a Souls game. From the gameplay impressions it sounds open world with multiple paths and optional confrontations.
Also you don't have any shield, replaced by guns though not powerful can be used to counter.
Miyazaki: "One of the core concepts that I've had even with Dark Souls and Demon's Souls is my mission and my goal is to make a very beautiful game. I know a lot of people have a hard time believing it when I sway those words, because that's not the first thing that comes to mind. I always believe that there is beauty in darkness. And so with Bloodborne, I feel like the darkness is darker, which means the beauty is going to rise - and you'll be able to really see that beauty out of the darkness."
hahaha this man is Sick
