The second downloadable episode for Tomb Raider: Underworld - Lara's Shadow will be released later this month. But you won't be playing as Lara Croft this time around, but as her clone the Doppelganger. The Doppelganger has access to special shadow powers that allow her to slow down time in order to get her attacks in and she also has increased agility. Check out the developer's diary below for more details on Lara's... uhmm, the Doppelganger's adventures.
