Here's the debut trailer for Rain (working title), Sony Japan's new PlayStation Network exclusive.
Sony announced the game at its Gamescom press conference yesterday,describing it as "a story of an invisible world only revealed by the rain".
Details were otherwise scant, but the trailer appears to show an indivisible boy who can only be seen in the rain exploring various urban environments. It also hints at stealth elements which see the boy sneaking to avoid some sort of invisible creature, which gives chase when he knocks over some objects.
There's currently no word on a release date.
