Metal Slug

Blast through jungle bases and snowfields with a heavy machine gun and a stolen tank in this pixel-perfect arcade classic.

Metal Slug isn't just a shoot-'em-up; it's a masterclass in side-scrolling chaos. You play as Marco or Tarma (or both in co-op) and sprint left-to-right through jungles, cities, and underground labs, mowing down everything that moves. Your default pistol is fine, but the moment you grab a Heavy Machine Gun or a spread-shot, the screen lights up with particle effects that still feel great decades later. The real star is the Slug itself — a chunky, metal tank that turns any firefight into a demolition derby. I remember finding the first one parked near a crashed plane, climbing in, and immediately driving it off a cliff while shooting backwards. You can even eject right before it explodes and the tank will plow forward, taking out a whole group of enemies. That kind of emergent chaos is why people still boot this up. POWs pop out of the background and give you points or weapons; hidden items are tucked into destroyed buildings. It's tough, though. One hit kills you unless you're in a vehicle, and continues are limited. The old arcade greed is real. But that tension is what makes each run feel like an action movie you control. If you can grab a friend for two-player, do it — the screen gets messy, bodies fly everywhere, and the last level turns into a full-on sci-fi war. Just watch your ammo, because the pistol feels like a peashooter after you've tasted the Flame Shot.

Arrow key.

Save your heavy ammo for boss fights; weak enemies die to the pistol just fine. In the tank, use the cannon for groups and the machine gun for airborne enemies. Rescue every POW you see — some drop weapon upgrades or bonus points. Keep moving forward slowly; enemies spawn from behind too. Learn boss patterns before unloading your best weapon. Always check behind breakable walls for hidden items.
