You're pined behind a half-sunken jep, zombies pouring in from the left, a giant crab mech charging from the right, and your only way out is a stolen tank and a lot of trigger discipline. Metal Slug 3 is a run-and-gun arcade classic where you blast through five increasingly unhinged missions packed with enemy soldiers, mutant boses, and vehicles you can hijack mid-level. You move, shoot, throw grenades, and make split-second calls about which weapon to save for the next screen — every level branches into alternate routes with different enemies and rewards. Play Metal Slug 3 free right here with no downloads, no installs, just the game loading straight in your browser. Think you can survive long enough to see the final boss?
How to Play & Controls
- Arrow Keys / WASD — move and crouch
- Z / A — shoot (hold for rapid fire)
- X / S — jump
- C / D — throw grenade
Tips & Tricks
- Stockpile grenades before boss fights — they do massive damage and most boses have a short invincibility window you can skip right through.
- Take alternate route branching paths at least once; they hide better weapons and extra lives that make the late game much more forgiving.
- When you're riding a vehicle, jump out before it explodes to keep your weapon — losing the slug doesn't have to mean losing your gear.
