Eidos has kept quiet over suggestions that new Lara outing will be called Tomb Raider: Underworld.
Suggestions it would don the title erupted after the publisher filed a US trademark for the name, spotted by the keen eyes of specialist site Trademork.
The filing will apparently cover both retail and digital distribution of the game, hinting that we could see it offered on Live in a similar way to Tomb Raider: Anniversary. Or it could mean we will simply be offered it on Steam like the rest of Eidos' catalogue.
Additional details are scant, other than rumblings it will be centred around the last five days of the Mayan Calendar, where portals between our world and the Underworld open and let nasty things have their way.
Eidos unveiled plans to expand on its Tomb Raider series earlier this year in a financial statement, alongside with promises it would extend Hitman, Just Cause and Championship Manager franchises.
Meanwhile those of you hungry for a bit of Lara should pop over to our Tomb Raider: Anniversary review to find out why it scored nearly top marks.
