And yet, every year in Tokyo, Seoul, and São Paulo, hundreds of players gather—not to play Street Fighter or League of Legends , but to compete for milliseconds and pixel-perfect positioning in one of the most unforgiving speedrun and score-attack circuits on the planet. Welcome to the world of Metal Slug competitive play. The Metal Slug esports scene didn’t emerge from a publisher’s marketing budget or a venture capital-funded league.
