All this talk of retro-platforming shooters going FPS just makes me think of Maverick Hunter.
Unreleased Mega Man FPS Game: The Complete Demo [Maverick Hunter] [All Known Footage]
Honestly, I think that might have been pretty cool.
Yeah. I thought that had potential. it was being worked on by some Retro Employees who worked on metroid prime.
people get all scared when they hear "FPS", generally because generic war simulator FPS call of patriots of honorduty 15 gives it a bad name.
but there are tons of great FPS games, like Portal, Half Life, Doom, Duke Nukem 3D, and of course, Metroid Prime. Metroid went from 2D to 3D first person, and it's considered "Super Metroid in 3D", and one of the best games in the franchise.
Maverick Hunter also took the best bits of plot from the former games and incorporated a bit of Zero series too. it was X and Zero, fighting Mavericks as usual, it was going to be a 3 part series, where in the third, you would play as Zero, taking down a power mad X, a-la Zero 1.
