The game uses a 2D side-scrolling perspective where players advance through stages, shoot enemies with standard series weapons, throw grenades, and pilot Metal Slug vehicles. Its overall stage flow closely follows Metal Slug 3, but some enemy waves, visual assets, attack patterns, and character appearances are modified. Success depends on memorizing spawn points, reacting quickly to altered bullet patterns, using jump and crouch correctly, and managing weapon pickups through branches and boss fights.

Eri Kasamoto

Since this version modifies Metal Slug 3, original-stage knowledge helps but does not guarantee safety. Focus on survival first and learn where changed enemies appear before chasing prisoners or score. Use crouching often against horizontal fire, save grenades for dense groups, and avoid overcommitting in vehicles when the screen becomes crowded. In boss fights, spend a cycle reading altered attack timing, identify safe zones near the screen edges, then commit to damage during openings.
Tips and tricks
Use Metal Slug 3 route knowledge as a base, but expect enemy placements to differ.
Tips and tricks
Shotgun and Thunder Shot are especially valuable for quick crowd control.
Tips and tricks
If a boss pattern looks unfamiliar, survive one cycle before trying to optimize damage.
User Reviews

User Reviews
The core feel of Metal Slug 3 remains fun, though the balance is rougher than the official game.
