First details on the ICO and Shadow of the Colossus developers PlayStation 3 project may have just leaked online, just a few weeks before the game was expected to make an appearance at E3.

The alleged trailer for "Project TRICO," by way of PlayStation Lifestyle, begins with a scene that might be familiar to followers of Team ICO's work. The PlayStation developer teased the opening imagery in a job recruiting ad that ran last year. The rest will look completely new.

The Project TRICO trailer shows the interaction of a young boy who bears a striking resemblance to the lead character in ICO and a giant animal that looks part feline, part rodent—a giant feathery, furry thing that has clearly had its wings clipped. The trailer shows off possible gameplay mechanics that fit in with previous Team ICO games, namely cooperative platforming over architecture that fits in aesthetically with the series.

The purported teaser also highlights thematic elements present in ICO and Shadow of the Colossus—the latter, at one point, code-named "NICO"—and looks like it could fit in the same universe.

Team ICO lead Fumito Ueda spoke briefly about the still unannounced game at this year's Game Developers Conference, saying "the essence of the game is similar to ICO."

We've contacted Sony Computer Entertainment America reps to verify if the trailer is genuine.
