Metal Slug at 30: How a 1996 Arcade Run-and-Gun Became the Peak of Pixel Art
SNK is marking 30 years of Metal Slug with a series reboot and, in the company's words, "a wide range of projects including new ones." It's a good moment to look back at a series that, for a stretch of the 1990s, did hand-drawn 2D animation better than anyone in the arcade.
The 1996 debut and the Nazca pedigree
The first Metal Slug hit Neo Geo arcade cabinets in 1996. It came from Nazca, a studio built by ex-Irem staff who had worked on games like Gunforce and In the Hunt. You can see that DNA in the first Metal Slug: a run-and-gun where two soldiers mow down waves of enemies, climb into the tank the series is named after, and watch the screen fill with explosions.
What set it apart wasn't the shooting. It was the animation. Enemies didn't just blink out — they flinched, staggered, and collapsed in distinct ways. The tank idled and rolled with personality. Even the hidden POWs were drawn with care.
Why the pixel art still holds up
Ask players today what they remember and you'll get the same answer every time: the sprites. On the r/Games thread announcing the reboot, the top sentiment wasn't about new games at all — it was about the art.
One commenter put it plainly: Metal Slug was the high-water mark for 2D sprite animation. Another called it the 90s Cuphead. Thirty years on, with a whole indie scene built on pixel art, the originals still hold their own against a new generation of artists.
That's a strange thing for a run-and-gun to be remembered for. It's also why the word "reboot" carries real risk here.
A story lighter than it looks
Metal Slug has never been story-first. Plenty of fans will tell you there's barely a plot. But there is one, and it's stranger than most people remember.
A rebel army led by General Morden — a Canadian, oddly enough — fights the world government, gets tangled up with Martians, and eventually drags in a second alien species. The timeline doesn't even run in release order: it goes 1, 2/X, 3, 6, 4, 5, 7/XX. Along the way there are clones, impostor generals, and enough "why is this happening" to fill a small wiki.
None of that was ever the point. The point was always the four soldiers — Marco, Tarma, Eri, and Fio — and the chaos around them.
What "reboot" actually means here
This is where fans get nervous, and for good reason. SNK tried a "reboot" once before: Metal Slug 3D, a 2006 PlayStation 2 game that pushed the series into blocky polygonal 3D. It sold poorly, never left Japan, and is remembered mainly as a cautionary tale.
The more recent Metal Slug Tactics (2024) showed SNK will branch out — but it split opinion, too. The thing players keep circling back to is simple: don't lose the pixel art. More than one commenter said they'd be annoyed if the reboot went the "2.5D vector" route so many modern revivals take.
The counterpoint is worth hearing. There's real pixel-art talent out there today, and the original developers are already building a spiritual successor — Black Finger JET — which is sitting on Steam wishlists right now.
