Samus Aran is the protagonist of Metroid Prime 2: Echoes. Clad in her iconic Power Suit, she is equipped with a versatile arm cannon and the ability to transform into a compact Morph Ball. Her core abilities include the Power Beam, a standard energy weapon, and the ability to jump. As the game progresses, Samus acquires numerous upgrades that enhance her suit, weapons, and movement capabilities, allowing her to overcome increasingly difficult challenges.
Samus's resilience is tied to her Energy Tanks, and her offensive capabilities are bolstered by Missile Expansions and Power Bomb Expansions. Her tactical options expand with each new beam weapon (Dark, Light, Annihilator) and suit upgrade (Dark Visor, Echo Visor, Gravity Boost, Screw Attack). Understanding Samus's base capabilities and how each upgrade modifies them is fundamental to success.
