Tomb Raider Walkthrough: Guilty Conscience - Hall of Ascension (Part 7)

Lara Croft must regroup with Roth and tell him what happened to the plane and pilot. She finds out that the co-pilot of the plane that went down is alive. She wants to go find him, but Roth tells her it's not worth it because we have our own people to take care of. Lara, however, goes to find the co-pilot anyway because she does not want to have a guilty conscience. Afterwards she finds another secret tomb. This optional tomb is called "Hall of Ascension."
