Bokeh Game Studios’ Slitterhead is one of the strangest games I’ve ever played, for better or worse. The product of collaboration by several Silent Hill alumni, including series creator Keiichiro Toyama and composer Akira Yamaoka, Slitterhead is actually more of a spiritual successor to the Siren series. Difficult to categorize, it features elements of stealth games, detective games, action RPGs, and puzzle platformers, all wrapped up in a body horror bow.
