Japanese developer NITRO PLUS has announced Dolls Nest, a mysterious new sci-fi game developed in-house with their animation team.

Dolls Nest is being developed for Windows PC (via Steam), though a release date wasn’t announced.

Planning and graphics for Dolls Nest are being handled by internal studio NITRO ARTS (formerly Nitroplusarts) while NITRO PLUS is handling production.

NITRO PLUS president Takaki Kosaka talked up the new game, noting it’s their first “genuine in-house game in a while” and that their teams are “putting all their efforts into development.”

Here’s a teaser trailer for the new game:
