Metroid Prime 2: Echoes 2004

Is it still worth playing?

Retro Studios' 2004 first person action adventure for the GameCube, with platforming, shooting and puzzles in an interconnected world. Samus is sent to rescue Galactic Federation Marines near the planet Aether and finds them slaughtered by the Ing, a hostile race from an alternate dimension of the planet. That planet is two worlds at once. Light Aether and Dark Aether are parallel dimensions, and the atmosphere of Dark Aether damages Samus, so she relies on safe zones there. In both she uses a scanner visor, a dark visor and an echo visor, and most weapons use ammo. Multiplayer supports four players in Deathmatch and Bounty modes. Crossing between two worlds, one of which wears her down away from safe zones, still makes every route a puzzle today.
