Yukio Futatsugi’s studio Grounding are working on a game about… school children murdering each other.
However, Futatsugi’s team will only be providing the engineering talent, with the writing, direction, music, and art being done by a different team and creative vision. So it’s not really a Grounding game.
The game seems too weird for something that I would play, but maybe there’s some appeal here that I’ve overlooked? Battle Royale games are popular these days, so I assume it makes business sense for Grounding to participate in the development in order to keep the studio afloat.
