How it plays

How does Metal Slug: 1st Mission play?

The game uses a side-view perspective. The player advances through discrete missions, defeats infantry and machinery, avoids hazards, and reaches the end of each stage while managing health and ammunition-related pressure.

On-foot movement centers on running, jumping, firing, and using available weapons. Some sections place the player in Metal Slug vehicles, changing the rhythm and allowing heavier attacks. Progression comes from completing missions and learning the layouts, enemy placements, and timing of each stage.

Plan your run

What is the best way to play Metal Slug: 1st Mission?

Keep moving, but avoid rushing into unfamiliar screens. Short jumps and controlled bursts are safer than firing while blindly advancing.

Study enemy placement and prioritize threats that can block movement or attack from above. In vehicle sections, use the vehicle's firepower aggressively while watching for hazards and incoming attacks.
