Metroid (MercurySteam prototype)

Metroid (working title) was a prototype pitched by Spanish developer MercurySteam to Nintendo in early 2015, that appears to have been unsuccessful.

History
Anonymous sources who were in contact with the fan news site Nintendo Life described the prototype as a "first-person game set in a post-apocalyptic sci-fi environment". Samus Aran would have been playable, along with seven other Bounty Hunters, similar to Metroid Prime Hunters (it was not revealed whether these Hunters would be new characters or the same Hunters from Hunters). Had it been greenlighted, the game would have been released for Nintendo 3DS and Wii U. MercurySteam did not make any secret of the fact that they were working on a Metroid project when interviewing prospective employees, which likely hurt the project.

MercurySteam has now updated their website with artwork of a cigar-smoking man sitting in a futuristic cockpit, with this text: "Exploring new worlds, fighting strange creatures, discovering new heroes." This may suggest that they have retooled the prototype into a new IP.

It is the second Metroid pitch Nintendo is known to have rejected, after Next Level Games' Metroid prototype.
