On November 21, 2007, video game developer Eidos Interactive filed to protect the trademark Tomb Raider Underworld in relation to, what else…a video game. Mork suspects that this might be the name of Tomb Raider 8, which is currently in development at Crystal Dynamics.
The storyline is rumored to be based around the Mayan Calendar. During five nameless and dangerous days at the end of the calendar called Wayeb’, portals between the mortal realm and the Underworld dissolve, allowing ill-intending deities to causing disaster and mayhem.
Sounds like an exciting premise and setup for the next Tomb Raider installment.
