If you are wondering why there hasn’t been a Metroid game for the 3DS yet, so are we. Apparently, however, there has been thoughts about it. Next-Level Games, the studio behind Punch-Out!! and Luigi’s Mansion Dark Moon were at some point working on a Metroid game for the 3DS.
The concept art is very interesting, in that it looks strikingly different from anything we have seen from the Metroid series so far. It’s very blocky and angled, a lot different from Samus’s normal huge rounded shoulder pads. Apparently the game never really got off the ground, being described as very “bare-bones.” It was shelved in favor of Luigi’s Mansion 2 instead.
Still, it gives us hope that we will see a Metroid game on the 3DS soon enough.
