Ratchet & Clank developer Insomniac Games will reveal its next game at 2.30pm GMT tomorrow, January 28, according to a brief teaser trailer released yesterday evening.

As you can see in the trailer it appears the game will bet set, at least in part, under the sea, and asks viewers to “dive deeper” on Thursday.

The footage also features what is either ancient ruins which are now submerged, or signs of an underwater civilization.

Our interest has been piqued.
