Plastic Studios, developer of oddball PlayStation 3 titles Datura and Linger in Shadows, has announced new PS4 project Bound.
Developed in collaboration with Sony Santa Monica, Bound will be an experimental 3D platformer starring a female character who moves via dancing.
Writing on the EU PlayStation blog, director Michal Staniszewski described the project as being "unique in visual style, narrative storytelling and also mechanics".
Judging by the trailer, Bound looks like it will be difficult to categorise.
"Bound is a 3D platformer designed for people with the desire to concentrate on the narrative side of games and experience a mature story," Staniszewski continued.
"On the other side of the spectrum, Bound is also being prepared for hardcore gamers looking for the challenge of one big puzzle that can be only solved by a community of players working together.
"In result, we are going to deliver a 'notgame' to you, which is also a game. It's up to you to decide how you would like to play."
