Walkthrough: You begin your mission by landing on SR388. Before you begin, remember to go back to your gunship if you ever are in need of healing up, restoring ammo, or saving your game file. By heading to the right of the ship, you will start your journey by learning the basic Controls of the game. Instructions will appear on the screen, not going away until you perform the action themselves.
After learning the ropes and reaching the end of the first room, Samus will come to a yellow door. With a simple shot with her Weapon, the door will open. Here, a player will learn even more maneuvers. After practicing all your new moves, break through the rocks from below to reach your first Ammo Refill Station.
From here, use a missile to break through the red barrier around the next yellow door. Head inside to find your very first Chozo Statue. Simply shoot the orb in the Statue's hand to reveal the Morph Ball. By hopping onto it, a player will acquire the Morph Ball into their arsenal. After adding the Morph Ball to your Power Suit, head to the small passageway below the Statue that is blocked with rocks. Destroy the rocks and defeat the awaiting enemy, and then enter the path using the Morph Ball to proceed.
Missile Expansion: After gaining the Morph Ball, return to the very first room apart of the Surface Area. Shoot the enemy in the small crevice to the left, and then enter it using the Morph Ball. This will lead you to the first Missile Expansion found in the game.
