The player begins the mission at the base of the structure, and must work their way up through the inside of the tower, destroying the generator turbines as they go. The structure is defended primarily by Normals and MTs at the base, as well as drones armed with high-explosive bombs further up inside the tower. The mission ends after all of the generator turbines are destroyed. Hard Mode Differences: Once all of the turbines are destroyed, three Fermi aerial fortresses will appear above Megalis to prevent the player's escape. All three must be destroyed to complete the mission.
