We downloaded and ran METAL SLUG 3 on a standard Windows 10 machine to bring you a hands-on look at this classic run-and-gun shooter. The game arrives as a direct GOG installer, and after installing it ourselves we can confirm it boots quickly and plays exactly like the arcade original. If you grew up pumping quarters into a cabinet, this release is a faithful trip back. If you're new to the series, it's a fast, chaotic, and surprisingly deep 2D action game that still holds up.

About METAL SLUG 3
METAL SLUG 3 is the pinnacle of the classic 2D run-and-gun formula. You take control of Marco, Tarma, Eri, or Fio as you blast your way through six sprawling missions packed with relentless soldiers, towering bosses, and the series' signature goofy humor. The pixel art is vibrant, the animation is fluid, and the action never lets up. What sets this entry apart is the sheer variety: one minute you're fighting through a jungle, the next you're riding a camel, piloting a submarine, or turning into a mummy. It's a game that constantly throws new ideas at you, and that's exactly why it remains a fan favorite.
In our playthrough, the controls felt responsive and the difficulty curve was just right—challenging but fair. The cooperative multiplayer mode is a highlight; grabbing a friend for local co-op turns the chaos up to eleven. We also appreciated the inclusion of vehicles like the Metal Slug tank and the Slug Flyer, which add a layer of strategy to the run-and-gun mayhem. If you enjoy titles like Tears of Metal or UnMetal, this one belongs in your library.
