Retro Studios is ramping up talent acquisition for a variety of crucial roles, sparking rumors that development for Metroid Wii U is underway.

"As a wholly-owned subsidiary of Nintendo with an outstanding track record with its games, it's not unreasonable to expect that the studio's next project will be an important release," said Nintendo Life.

Among the several postings, there are five job advertisements for high-level profiles including Senior Tools Engineer, AI Engineer, FX Artist, Tools Engineer and Gameplay Engineer.

Four out of the five positions will require work on 3DS/Wii U, while the last one will possibly juggle tasks across all Nintendo consoles.

The last Metroid released was 'Metroid: Other M' for Nintendo Wii in 2010.

It garnered polarizing reviews from media and gaming pundits, with disappointing long-term sales.

The first-person adventure originated in 2002, when Retro Studios released GameCube's Metroid Prime, a first-person adventure shooting game.

Nintendo has been struggling with their financial output and market grip for quite a while now.

The company is still looking for its saving grace, but, Forbes' Erik Kain might have the answer.

"Metroid Prime was easily one of the best GameCube games ever made, and one of the best first-person shooters to release on any system. The franchise—which took the old 2D Metroid gameplay and transformed it into a first-person perspective, while retaining many of the elements of exploration, puzzles, and platforming—began on GameCube and made its way to the Wii, though we haven't seen a new entry on the Wii U."

He said further, "Nintendo doesn't release very many first-person shooters, but when they do they tend to be excellent. This is no surprise, really, given Nintendo's standards for excellence in its first-party releases."

Developers started throwing around ideas for a Metroid Wii U in 2013.

It could be high time to turn those creative ideas into reality.
