Energy Part 1
Energy Part 2
Samus must unleash a Power Bomb in the elevator room beside the Bottle Ship Control Room and kill the Desbrachian. Beyond here is the Bottle Ship Residential Area.

Missile Tank 1
Immediately after killing the Brug Mass and being welcomed onto the 07th Platoon, Samus must return to the long hall before the Control Room. A Geemer will come out of a grate in the floor, Samus must enter it in Morph Ball mode and follow the tunnel to the end.
Missile Tank 2
In the "conference hall", Samus must climb the stairs and proceed behind the glass chamber. She must dislodge a grate with a Missile and then roll through a long tunnel in Morph Ball mode. This will take her to a catwalk in the Spaceport, on which she will find the Tank.
Missile Tank 3
Missile Tank 4
Missile Tank 5
Missile Tank 6
In the tall room, the same room where the Accel Charge is obtained, Samus must activate the terminal at the top to cause several platforms on the walls to straighten. One of these will contain a glowing opening to a tunnel.
Missile Tank 7
Following Samus's order to go to the Biosphere, she must ascend the elevator outside the Control Room and enter a long corridor with three vents in the ceiling. The one closest to the exit door has a Fly Pod in it; Samus must destroy it and Kick Climb up the vent.
