the planet's core, where she finally defeats Dark Samus and then the corrupted Aurora Unit 313. As a result, Dark Samus is obliterated, and Phaaze explodes, rendering all Phazon in the galaxy inert. The Federation fleet escapes Phaaze's destruction, but loses contact with Samus in the process. Samus eventually appears in her gunship, and reports that the mission is accomplished before flying off into space. Samus returns to Elysia, where she mourns the loss of her fellow bounty hunters. If the player completes the game with all of the items obtained, Samus is seen flying into hyperspace, with Sylux's spaceship following her.

At the Media Summit held by Nintendo in May 2007, Nintendo of America president Reggie Fils-Aimé said that Metroid games "never played this way before" when referring to Corruption. He also noted that Nintendo employees who had seen the game in action claimed that it "will reinvent the control scheme for a first-person shooter". Game director Mark Pacini stated that the biggest concern Retro had during production was the controls, which had "too many functions for the amount of buttons". Pacini also said the Wii Zapper, a gun shell peripheral, was never considered because it was unveiled when the game's development was almost done. Retro president Michael Kelbaugh said that the delays for the game's release gave them more time to tune the controller, which took a year. He also stated that while Retro did "a
