Toyama's Bokeh Game Studio was founded on August 13 and announced publicly in December. Speaking with IGN Japan, the acclaimed developer explained that he is working on “an action-adventure game that will appeal to fans of my previous work”. He explained that the game will include “battles and story elements” in the kind of richly authored worlds you might recognize from his games at Sony’s Japan Studio and Konami.

When pressed on whether this new title will lean more toward the horror themes of Silent Hill and Siren or the cuter anime-styled paranormal setting of Gravity Rush, he explained, “If anything, this will be more of a horror-oriented game. But we will focus on making this a broader entertainment experience, rather than a hardcore horror game.”

While Toyama has been a first-party Sony developer for the past 20 years or so, he said that this new game will be a multi-platform release. “We are developing with PC as the lead platform, but we hope to release the game on as many console platforms as possible,” he said.
