Metroid Prime 2: Echoes

Metroid Prime 2: Echoes, released in 2004 for the Nintendo GameCube, is a first-person adventure game that builds upon its predecessor while introducing several unique elements: 1. Dual-world mechanics: The game features Light and Dark versions of the planet Aether, with players switching between dimensions to solve puzzles and progress. 2. Beam system: Unlike the first Metroid Prime, beams don't stack. Instead, players must switch between four distinct beams (Power, Dark, Light, and Annihilator) for combat and puzzle-solving. 3. Ammunition: Dark and Light beams use limited ammo, adding a resource management aspect to combat. 4. Enhanced scanning: The scan visor now includes a zoom function for distant objects and provides more lore through Luminoth and Space Pirate logs. 5. Increased difficulty: Generally considered more challenging than its predecessor, with tougher bosses and environmental hazards. 6. Multiplayer mode: A first for the series, featuring deathmatch-style combat for up to four players. 7. Dark Samus: Introduces a new antagonist, a corrupted Phazon-based doppelganger of Samus. 8. Suits: Features the Dark Suit and Light Suit, which provide protection against dimensional hazards. 9. New abilities: Introduces the Screw Attack, Sonic Boom, and Echo Visor. 10. Atmosphere: Emphasizes isolation and a darker tone compared to the first Metroid Prime. The game's unique dimension-shifting mechanics and challenging gameplay make it stand out within the Metroid Prime trilogy.
