Metal War is a free online 2D platform shooter that puts you in the middle of non-stop combat arenas where surviving means outgunning, outrunning, and outsmarting waves of enemies. You move fast, shoot faster, and every second of hesitation costs you. The side-scrolling battlefield keeps the pressure constant, and there's no downtime between encounters.

The game rewards players who think on their feet. Weapon upgrades let you swap out weaker gear for heavier firepower as you progress, and power-ups scattered across levels can flip a losing fight in your favor. Controls are tight and responsive, which matters a lot when you're dodging projectiles while lining up shots. The combat arenas are designed to push your reflexes hard – platforms at different heights, enemies coming from multiple angles, and limited space to maneuver.

If you enjoy free action platform games, run-and-gun shooters, or side-scrolling combat games online, Metal War hits that exact sweet spot. It's a solid pick for anyone who wants a quick skill-based challenge without downloading anything. Single-player mode gives you a focused, high-intensity experience that works well for short sessions or extended grinding to unlock better weapons. Fans of classic 2D shooters and arcade-style action games will feel right at home blasting through every wave Metal War throws at them.
