You may not be able to play Bloodborne on PC, but you sure can pretend with this Dark Souls mod.
Aptly named BloodSouls, the mod adds the Hunter character model along with the Saw Cleaver and Blunderbuss, two of the most recognisable weapons in Bloodborne.
It also changes up the HUD icons and the rest of the game sounds to resemble those of Bloodborne’s. If you’re curious, the Saw Cleaver is a replacement for the Dark Sword, and the Blunderbuss takes the Light Crossbow’s place.
It’s not ideal, but it’s the best we could have given Dark Souls’ limitations. You also can’t side-step, so you’ll continue to employ rolling to avoid hits.
The mod relies on DSFix (which you should be using anyway), and DSMODT to load in new textures. You can download it yourself and read the install instructions through here.
