Microsoft is continuing its streak of securing exclusive downloadable content for cross platform games. The latest title to benefit Xbox gamers in this way is Eidos’ upcoming Tomb Raider: Underworld. The company states that the chapters will contain up to six hours of new gameplay for the title. The first of the DLC chapters is expected to be made available before the Holidays.

The question that we’ll all have to find out soon is whether or not Tomb Raider is still a big enough franchise for the exclusive DLC to even matter.

Gamers can look forward to the demo hitting Xbox Live Marketplace later this month.
