Which game should I start with?
Metal Slug 1 introduces the core rhythm of moving, jumping and firing across six missions. Metal Slug 2 adds character choices and transformations, while Metal Slug X remixes that adventure with revised enemy and weapon arrangements. Metal Slug 3 has branching routes; its five main missions can offer different paths on later runs. Metal Slug 4 has six main missions, and Metal Slug 5 has five.
Use the game guides above for each title’s controls, mission structure and first-run tips. The 34-mission total counts main missions, not every branch as a separate level.
