Via VG247, Luto Akino, a programmer and digital artist, is working on a Metroid 64 fan game:
The environments right off the back certainly look like they would be from an N64 game, and also suitable for the general moody and frightening atmosphere in the Metroid series.
It also sees Samus running, jumping, and rolling around the place, though currently it is just a small, basic location. A shooting mechanic is also in place, which seems to have some kind of lock-on, obviously necessary for a console that only has one analogue stick. It’s a really cool early take on a potential N64 version of Metroid, so probably worth keeping an eye on to see how it develops.
