About METAL SLUG
Metal Slug returns to Steam as the inaugural entry of SNK’s classic 2‑D run‑and‑gun series. Players guide the iconic soldiers Marco and Tarma, piloting the titular tank across six arcade missions to stop General Morden’s plans. The port adds modern conveniences such as online co‑op, leaderboards, and full controller support while preserving the original arcade experience.
Beyond the main arcade campaign, the game offers selectable stages, solo or partnered play, and a suite of settings for control, language, video, and audio. It runs on Windows PCs (excluding Windows XP) and integrates Steam features like achievements, trading cards, and remote play options.
01 / THE GUIDE
Arcade Mode (Main Mission)
Arcade Mode reproduces the original arcade version, letting players control Marco and Tarma through six distinct missions. The mode emphasizes the classic run‑and‑gun formula, including the use of the Metal Slug tank to overcome enemy forces.
Progression follows a linear path, with each mission presenting new obstacles and enemy types. The goal is to defeat General Morden’s schemes by completing all six stages, staying true to the series’ original design.
- Focus on mastering the tank’s firepower for tougher enemy waves.
- Learn each mission’s layout to anticipate hidden power‑ups.

Mission Mode (Stage Select)
Mission Mode unlocks individual stages for selection, allowing players to replay favorite levels at any time. This mode supports solo practice or cooperative play with a partner on any cleared stage.
Players can train on specific missions without progressing through the entire arcade sequence, making it useful for mastering particular sections or experimenting with strategies.
- Use stage select to practice difficult sections before tackling the full arcade run.
- Coordinate with a partner to cover different enemy types simultaneously.

The feature requires an internet connection and utilizes Steam’s online infrastructure, enabling collaboration with friends or strangers worldwide.
