Metroid Prime 4 was first revealed at E3 2017 at the tail end of Nintendo’s E3 presentation. A giant number “4” appeared floating through space, followed by the Metroid Prime logo next to it, and then a single line of text that said “Now in development for Nintendo Switch” in what appeared to be Arial Bold font. If it sounds like I’m embellishing the reveal a bit here, that’s probably because this is literally the only glimpse we’ve ever had of Metroid Prime 4. No release window. No gameplay footage. No concept art, environment render, or even stock pose of longtime series’ hero and planet-hopping bounty hunter Samus Aran. Just.. a logo.
In a subsequent press release, it was revealed that the game was in development in conjunction with frequent Nintendo collaborator Bandai-Namco, a studio that had previously worked with Nintendo on things like Mario Kart Arcade and the last few Super Smash Bros games. Even though we had little to run with other than speculation and the now seemingly concrete reality that we’d soon be playing a brand new Metroid Prime game at home and on the go on Nintendo Switch, excitement for the series to finally return to consoles was palpable as dozens of excited reaction videos of the logo reveal were released all over the world. A new Metroid Prime game was finally on the way and every future Nintendo Direct, live stream, and earnings call had the chance of bringing with it even more exciting news of Samus’ next big adventure.
