According to a recent trademark filing by Eidos Interactive, the company has secured rights to the name Tomb Raider Underworld. It doesn’t take a rocket scientist to figure out that Underworld is probably the next installment in the Tomb Raider series.

The storyline is rumored to be based around the Mayan Calendar, taking place during the the five unnamed days at the end of the calendar named “Wayeb.” During the period of Wayeb, portals between the mortal realm and the Underworld dissolved, allowing hideous creatures to cause disaster and mayhem.
