Unlike previous Metroid titles where Samus gradually finds upgrades, in Other M, many of her abilities are present from the start but are 'locked' by Adam Malkovich's authorization. This narrative device dictates your progression and the strategic use of Samus's powers.
Key Authorized Abilities:
- Morph Ball: Essential for navigation and deploying bombs. Authorized early in Sector 1.
- Missile Launcher: Unlocks powerful projectiles and the ability to destroy Missile Blocks. Authorized in Sector 1.
- Power Bomb: Devastating area-of-effect weapon for combat and environmental destruction. Authorized in Sector 2.
- Diffusion Beam: Allows your Charge Beam to spread, hitting multiple targets. Authorized later in the game.
- Plasma Beam: A more powerful, piercing beam weapon. Authorized towards the end of the game.
- Ice Beam: Freezes enemies, useful for platforming and specific enemy types. Authorized late game.
- Screw Attack: Grants invincibility during a spinning jump and damages enemies on contact. Authorized late game.
- Space Jump: Allows for multiple jumps in mid-air, greatly enhancing vertical mobility. Authorized late game.
- Varia Suit/Gravity Suit: Reduces environmental damage (heat/lava, water pressure). Authorized as needed for specific sectors.
Adam's authorization is often tied to story events or reaching specific locations. You cannot manually choose which abilities to unlock; they are granted as the narrative progresses. This means you'll need to adapt your playstyle to the currently available arsenal.
