Slitterhead

Slitterhead takes places in the 1990s in Kowloon where mysterious monsters called Slitterheads are sighted killing humans.

It starts with a spirit-like being called Hyoki possessing a dog and multiple people before defending a girl named Julee against a Slitterhead. Julee ends up being a Rarity, a person who not only remains conscious during possession, but has special powers and abilities when possessed. Julee gives Hyoki the name Night Owl, based on an old legend about two spirits named Night Owl and Leopard Head who fight the Slitterheads.

In September 2020, Silent Hill creator Keiichiro Toyama left Sony Interactive Entertainment to form his own company, Bokeh Game Studio. A video posted by the studio in December of that year indicated that their first project would be an action-adventure game with horror elements. This title, Slitterhead, was first announced on December 9, 2021 at The Game Awards.

Bokeh Game Studio published a video diary on July 6, 2023, on pre-alpha testing that was underway in the same year.

Slitterhead received "mixed or average" reviews from critics, according to the review aggregator website Metacritic. 28% of critics recommended the game, according to OpenCritic. In Japan, four critics from Famitsu gave the game a total score of 34 out of 40.

Tristan Ogilvie of IGN praised the game’s unique body-swapping mechanics and blood-based combat, but criticized it for repetitive missions, limited enemy variety, and a shallow story that overstayed its welcome. Similarly, Greysun Morales of Game Rant praised the game's unique playable characters and premise, but criticized the plot, repetitive combat, and unclear progression.
