Super Metroid: Global Warming

About

After defeating Mother Brain and detonating Tourian, the shockwave of the explosion shifted the orbital path of Planet Zebes, moving it closer to the sun. Over time, the Zebian polar ice caps melted, leaving the entire planet submersed underwater. Samus returns to Zebes twenty years later to confront a second Mother Brain that spawned out of the depths, along with new dangers.
