Mission 13: Assault on the Supply Lines

"South of the Forerunner structure, a collection of thousands of spiked fock formations known as the Basalt Maze protruded from the moon's thick ice. Covenant supply lines were running straight through the Maze to set up defenses around the Forerunner structure. Spartan Davis connected with UNSC combat technicians who believed the could render the Forerunner structure inert. They just needed the chance to get inside the structure. Getting the combat engineers close to the Forerunner structure would be extremely difficult, so Davis created a diversion to provide them with the best chance. The Basalt Maze provided an ideal location for his plan."
