Crystal Dynamics is hard at work on their next Tomb Raider title, according to Eurogamer, which is due for release around Christmas 2011.

Their source confirmed the game for PlayStation 3, Xbox 360, and PC, however, was unable to confirm whether the game’s subtitle is ‘Downfall’.

Earlier this week, the portfolio of ex-Crystal Dynamics artist Joel Boucquemont was updated with a number of new artworks pertaining to what looks like post-apocalyptic destruction.

Last year in July, details leaked regarding a Tomb Raider reboot. Kotaku picked up the story detailing a reboot about a “young and inexperienced Lara Croft” investigating the tombs of an island off the coast of Japan after being stranded.

According to Eurogamer, the leaked document and this new Tomb Raider scheduled for Christmas 2011 are tied together.

The company has just completed the downloadable Lara Croft and the Guardian of Light and are now putting all of their attention towards the new Tomb Raider.

When reached for comment, Square Enix had nothing to say.
