Nintendo not planning Metroid: Other M door bug fix
A number of Wii owners are experiencing a mysterious bug in Metroid: Other M that, if encountered, will not allow the player to continue. The issue is related to a door on the far side of a lava pit, found in Sector 3. If that door happens to be red, it will not open as there is no alternative route to the next area. Don’t expect Nintendo to come up with a quick and easy fix anytime soon, though. Even though the company is aware that the title is causing problems for some gamers, a Nintendo Customer Support representative was only able to recommend loading an older save if possible or simply starting over.
Thanks to Captain N for the tip!
