Pt30 - Chasm Ziggurat. For the last stages of the game you go from SACRED PASSAGE and make your way over the bridge, and work you way up until you reach campsite ZIGGURAT VESTIBULE, and from there on for the final battle. After that you'll then go and deal with MATHIAS before saving SAM. Previous Pt29 - Chasm Shrine • Tomb Raider - Pt29 - Chasm Shrine
