Metroid Dread

Metroid Dread is a cancelled DS game for the Metroid series that was later reworked into the Nintendo Switch game of the same name. The game is notable for being in development hell, having been originally developed for the Nintendo DS. This early version of the game has never been publicly shown off. This early version has the same basic premise as the final one, with Samus trapped on an alien world, trying to survive against an unstoppable foe.

No prototype builds or ROMs have ever surfaced for this DS version, and it is unlikely Nintendo will release any. It's a possibility that concept art or screenshots of this early version will be revealed in the upcoming art book, as Nintendo is open to talking about Metroid Dread's development history.

And in 2010, IGN's Craig Harris said in a podcast that he had seen a complete script for Metroid Dread, and that "Nintendo could use it anytime they wanted." It's possible that this was the synopsis that Liam Robertson was referring to. After the 2021 announcement of the game, Harris was asked on Twitter if he remembered anything from this script. He said he didn't
