Why players say this

Steam review verdict

Excellent co-op with branching paths and beautiful pixel art, but control issues, an overly long final level, and audio-video desync hold it back.

What players like

Excellent co-op experience: Co-op play, both local and online, is highlighted as a huge plus and a blast. The game provides great cooperative experiences for friends and family.

Branching paths increase replayability: The branching paths and alternate routes in each level significantly boost replay value. Players enjoy exploring different routes and discovering new content.

Beautiful pixel art: The pixel art is consistently praised for its beauty, detail, and timeless quality. Players note the detailed animations and charming graphics that have aged well.

Variety of enemies and vehicles: The game offers a massive variety of enemies and vehicles, including machine gun soldiers, tanks, mummies, aliens, submarines, mechs, and rideable animals. This variety keeps the gameplay fresh and engaging.

Longest and best in series: Players consider Metal Slug 3 the longest and most content-rich entry in the series. It is acclaimed as the best and the pinnacle of the franchise.

Common complaints

Control issues: Players report that controls feel weirdly bad, terrible, and unnatural, with laggy menus and input lag. This significantly harms gameplay responsiveness.

Final level too long: The last level is extremely long and difficult, often taking longer than the entire rest of the game combined. Players find it overwhelming and repetitive.

Extremely high difficulty: The game is brutally difficult, especially for 100% completion or for newer players. Some bosses have unavoidable attacks, and the difficulty can frustrate casual players.

Short campaign length: The campaign is very short, about one hour or under two hours, which feels lacking compared to modern standards and previous entries.

Terrible port quality: Players report that the port is poorly made and not recommended. This suggests the game suffers from multiple technical and quality issues that make it feel unfinished or unoptimized.

Gameplay and performance

Side-scrolling run-and-gun shooter: The game is primarily described as a side-scrolling run-and-gun shooter, with some vertical and top-down shoot 'em up segments.

Cooperative multiplayer supported: Players can enjoy the game with friends through local or online co-op multiplayer, supporting up to two players.

Branching path system: Levels feature branching paths and multiple route choices, breaking linearity and encouraging exploration and replayability.

Vehicle variety: A wide variety of combat vehicles (slugs) are available, including tanks, submarines, mechs, animals, and more.

Transformation mechanics: Players can transform characters into zombies, mummies, and other forms, which adds unique gameplay twists.

Audio and video desync issues: Multiple reviews mention audio desynchronization, where sound and visuals do not match, along with audio lag and general sound processing problems. Clusters 2, 11, 39, 47, 50 highlight this recurring audio issue.

Online co-op performance and crashes: Online cooperative play suffers from repeated crashes, poor FPS, lag, sound cutouts, and server issues, making the multiplayer experience unreliable. Clusters 5, 9, 12, 15, 49, 50 highlight these problems.

General poor performance and optimization: Many users report that the game runs poorly, especially on low-end hardware, with complaints about low FPS, stuttering, and overall poor optimization. Clusters 1, 17, 19, 31, 46 all indicate a widespread issue with the game's performance.

FPS drops in complex scenes: Frame rate drops are common when many enemies appear on screen or during complex, action-heavy scenes, causing slowdowns. Clusters 8, 10, 29, 35, 52 describe this performance degradation under load.

Crashes and freezing during gameplay: Crashes, freezes, and hangs are reported frequently, including crashes within minutes of gameplay, in both singleplayer and multiplayer modes. Clusters 5, 13, 20, 23, 42 document these stability problems.
