Sector 2: Mountain Base
While outside the base you'll need to examine the second window from the left. This will grant you control of your movement. Head up the hill towards the base and you'll come to an accel charger, which will allow you to charge up to full capacity much sooner.
Enter the Deleter
After meeting with the Federation scientist, you'll be attacked by a hidden Federation soldier--the Deleter--piloting a heavy mech. This giant is constantly on the move, so be ready to dodge constantly. You'll want to freeze the robotic arms with a fully charged beam before destroying them with a missile. After both arms are gone, fire at the engine on its back to destroy it completely.
After the battle, continue along the path to reach an icy cliff that is too steep to climb. Adam will authorize your shinespark, which will allow you to leap huge bounds after speed boosting. Use your shinespark to ascend into a low rafter. You'll only be able to navigate this area in your morph ball form. Be careful not to move quickly, as the enemies around can only be killed with your bombs. Find the exit on the north side, which will drop you down to the top of the cliff.
Adam will authorize the use of your wave beam, which will allow you to shoot through glass. Charge up a plasma shot and activate the target across the other room's window. This will start up the cargo lift in the previous room. Start heading back that way, but the entire cliff will start to avalanche. Use your speed booster to out move the raging snow and return to the inside.
Move up the platforms ahead. If one isn't stable, shoot it with your freeze beam to lock it in place. You'll eventually reach the elevator which will lead you to the top. You'll at first be attacked by Space Pirates. With your new more powerful plasma beam, they are hardly a threat. However, upon reaching the top you'll face a new horned enemy. It's much too tough to defeat now, so dodge and freeze it until it eventually flees. Continue to the waypoint and you'll locate a series of tubes. Use your morph ball to activate their buttons, draining the containers. Enter first person and you should be able to spot a new plasma target. Shoot it to unlock an extremely long duct that will take you back to Sector 3.
