While Metal Slug is legendary for its run-and-gun arcade action, its competitive scene operates differently than traditional esports like Street Fighter or League of Legends . There is no official Metal Slug league. Instead, competition thrives in two specific areas: speedrunning and co-op challenge runs (e.g., 1-credit clears or no-death runs). The "teams" are often communities or clans, and the "players" are elite record-setters.
