Metroid Dread is what many believe to be the title of a cancelled Metroid game. Supposedly, it's a 2D sidescroller for the Nintendo DS. "Metroid Dread" could also refer to a certain scan in the English (NTSC?) version of Metroid Prime 3: Corruption, which many people believed hinted at the existence of the game Metroid Dread. The scan has been removed in Japanese and later versions of Corruption.
