Doppelganger (Outfit)

Players can unlock the Doppleganger outfit by collecting a relic in the Egypt Chapter. The appearance of the Doppleganger is Lara with no skin as is the costume. The outfit allows for a new footstep sound effect, which sounds like someone stepping on a puddle of water but, really, it gives an illusion of hearing someone walking around with no skin.There were no new features added to this costume. These extra sounds were not included on the PSP version of Tomb Raider Anniversary.
