Metroid Dread Nearing Completion
Is the top-secret 2D Metroid DS game still alive? Well, maybe not, but
we can hope. Details inside.

August 27, 2007 - In 2005, IGN got hold of an official internal
Nintendo software list that revealed a number of key DS games set to
be announced in the future. All of the games on the list, including
titles like Super Princess Peach, were eventually announced and
released. All, that is, except for one -- a project known simply as
Metroid Dread.

To this day, Metroid Dread, thought to be a traditional 2D sequel in
the Metroid franchise designed specifically for Nintendo's dual-screen
handheld, has never publicly been acknowledged by the mega-publisher.
But an unofficial nod to the project has been found hidden within the
20-hour adventure of fantastic Wii first-person adventure Metroid
Prime 3: Corruption, developed by Retro Studios.

Players who journey deep enough into Samus Aran's Wii quest can use
Aran's scan visor to read lore and lob enemies and objects. Doing just
that on one mid-game world, we stumbled upon a panel with the
following message, quoted verbatim below:

"Experiment status report update: Metroid project 'Dread' is nearing
the final stages of completion."

Only two conclusions can be drawn from this message. One, Nintendo is
indeed still planning to release the DS game and gave Retro the okay
to hint about it in Prime 3. Or, the Texas-based developer is just
having a little fun at the expense of Dread hopefuls. Either way, it's
a great hidden inclusion in Corruption and we could not resist kick-
starting the Metroid Dread faith again.
