The Unfinished Swan, from indie developer Giant Sparrow, has been officially announced. It looks completely wonderful.

A PlayStation Network exclusive, The Unfinished Swan sees you navigating a pure white environment while flinging black balls of pain onto surfaces to guide you. It’s hard to describe and do it justice, so check out the trailer below to see it in action.

You play a boy called Monroe who is chasing a swan that escaped from a painting into a "surreal, unfinished world".

It looks like Sony are grooming developers Giant Sparrow as the replacement for thatgamecompany. The creators of Flower had a three game deal with the platform holder that expired with the release of Journey. Giant Sparrow creative director Ian Dallas says, "Sony calls it an ‘incubation deal.’

"In addition to giving us funding they also provide office space, equipment and advice." Part of the deal also sees a graphics programmer from Sony Santa Monica's God of War team bolstering the developer. "The best part is that we get to focus all of our energies on just making a game," says Dallas.

"Our goal is to give players strange and beautiful experiences they've never had before. We want to give people genuine surprises and then keep on surprising them the whole game.”

Intriguingly, Dallas says that what happens in the trailer is just the beginning. "The painting a white world stuff is actually just the first 15 minutes. After that, things get really weird,” he says.

The Unfinished Swan will be Move-compatible, not exclusive. No release date yet.
