Play Zero One Online
Dash through neon-lit corridors, blasting drones and nailing pixel-perfect wall jumps—this forgotten GBA gem plays like Mega Man on a caffeine rush.

Zero One on the GBA is one of those games you stumble onto years later and go, "Wait, how did I miss this?" It’s got this slick cyberpunk energy—like if someone took Mega Man’s tight controls, gave it a graffiti-tinged aesthetic, and cranked the speed up just enough to keep you on your toes.
First thing you’ll notice: the movement feels good. Your little android dude (or gal? never quite clarified) dashes, wall-jumps, and shoots with this satisfying snap. The levels are short but packed—you’ll blast through drones one minute, then hit a sequence where timing jumps between disappearing platforms actually makes you hold your breath. And yeah, the neon-soaked visuals? Pure early 2000s GBA magic.
It’s not perfect—some enemy patterns feel cheap until you memorize them, and the story’s basically a cryptic post-it note—but that’s part of its scrappy charm. Finished it in an afternoon and immediately wanted more. If you’ve got a soft spot for forgotten gems, this one’s worth digging up.
