From Software's Bloodborne announced

During its E3 press conference, Sony showed off Bloodborne, the latest from From Software and Sony's Japan Studio and the apparent finalized name of the rumored Project Beast. It's coming in 2015, and a moody trailer shows off the grim spectacle.

A description accompanying the trailer says you're tasked with exploring the ancient city of Yharnam, as a curse now plagues the city. The result, apparently, is a lot of horrific things trying to kill you.
