The first information on Deus Ex: The Fall will be released tomorrow, a teaser trailer for the game has suggested.
The unannounced Deus Ex game, which is expected to be in development at Eidos Montreal, was teased on the game's official YouTube channel last night.
The 7 second video features the game's title and asks "Are we ready to begin", before closing with an 05/06/13 date.
It isn't yet known whether The Fall will be a follow-up to 2011's Deus Ex: Human Revolution or a spin-off.
A new Deus Ex title was first rumoured back in March after a series of domain names related to the series were registered by Square Enix.
