Explore the intriguing world of the Metal Slug series as we rank every game, showcasing their unique charm and gameplay. Find out which titles make the cut!

The Legacy of Metal Slug
I genuinely believe that Metal Slug stands tall as a hallmark in the realm of run-and-gun gaming. The art style, even today, is hailed as one of the finest examples of pixel art ever crafted, leaving its mark on countless players. But let’s dive a little deeper—while the original installments crafted by SNK are jewels of the arcade world, the series has seen its ups and downs over the years. After SNK’s collapse in 2002, the series took some detours that didn’t always land well. Still, depending on who you ask, there were some gems amid the rubble.
If you’re itching to jump into the Metal Slug universe, the usual recommendation is to start with Metal Slug 1, X, and 3, with 2 sometimes making an appearance in that mix. But if you find yourself curious and seeking more, buckle up! Here’s a complete rundown of the series, ranked from the least to most stellar entries.

A Few Important Notes Before We Begin
Before we rank, it’s essential to point out that numerous Metal Slug titles were released for older mobile phones, and even a few online games in certain regions. Due to the sheer volume, lousy documentation, and accessibility issues (a lot of these games have been delisted), I’m skipping them. Also, the pachinko machines? Let’s just say I have no way to compare those!

17. Metal Slug Awakening

When it comes to Metal Slug Awakening, the gameplay does capture a hint of the arcade classics. However, the free-to-play model is riddled with aggressive monetization tactics that can put a damper on the experience. Want to progress without endless grinding? Brace yourself to open your wallet for gear that will quickly become outdated with every new update. And the voice acting? Let’s just say the option to mute it was a lifesaver!
16. Metal Slug Defense

Metal Slug Defense adheres closely to the mobile tower defense genre, where you gather resources and dispatch units against opponents. While it offers the familiar Metal Slug visuals, the gameplay lacks depth. Though not entirely terrible, it thrives on addiction through frequent, minor progress, enticing you to spend more. On PC, where microtransactions are less prevalent, the moral issues lessen, but the gameplay still leaves something to be desired.
15. Metal Slug Attack

Struggling to differentiate Metal Slug Defense from Metal Slug Attack? You’re not alone. They essentially share the same foundation, with Attack introducing a gacha system for monetization. Though the newly released Metal Slug Attack Reloaded on PC and consoles has removed many microtransactions, it still leans heavily into addictive gameplay without offering a rewarding experience.
14. Metal Slug Touch

Metal Slug Touch is an oddity, featuring just four vehicle-based levels controlled entirely through touch. While it’s not a freemium title, it’s quite lacking in substance. Although it resembles the series, borrowing heavily from its arcade counterparts, the effort feels minimal. You might find it hard to even purchase this game today, given its incompatibility with newer devices.
13. Metal Slug Advance

At first glance, the Game Boy Advance seemed like the perfect platform for Metal Slug. But Metal Slug Advance left many puzzled with its lackluster execution. While it mirrors the arcade aesthetic, it indeed lacks the vibrant energy we expect. A health bar instead of instant death dampens the gameplay, making it feel slower and less engaging. Some exploration elements were added, but they didn’t quite breathe life into the experience.
12. Metal Slug 7/XX

Metal Slug 7 made its debut on the Nintendo DS, and while it was commendable for its time, it doesn’t shine as brightly today—especially when compared to Metal Slug XX. The gameplay remains solid, transitioning to intriguing settings, but it lacks the excitement and flow that defined earlier titles. While it’s not a complete flop, it certainly occupies the lower rung of the series.
11. Metal Slug 1st Mission

When SNK aimed to adapt its arcade hits to the NeoGeo Pocket, Metal Slug 1st Mission was among those ambitious projects. While it captures the essence of the series, it lacks detail and flow due to hardware limitations. The new characters introduced don’t quite fill the shoes of the beloved protagonists, but it manages to stay closer to the formula than Metal Slug Advance did.
10. Metal Slug 3D

Metal Slug 3D struggles to connect with fans of the franchise due to its awkward execution of 3D mechanics. While the concept of a 3D shooter is enticing, this title presents a series of short missions in tight spaces with slow pacing. It lacks the charm of the traditional 2D graphics but does offer a unique visual experience. Curiously, it never saw a release outside Japan, leaving many fans scratching their heads.
9. Metal Slug 4

After SNK’s bankruptcy, Metal Slug 4 found itself under new developers, Mega Enterprise and Noise Factory. Though the core gameplay remains intact, the creativity is noticeably missing. Recycling past elements and introducing new characters was a gamble that didn’t pay off well. Fans of the original might find this iteration passable but unremarkable.
8. Metal Slug 6

Metal Slug 6 marks a departure from the classic NeoGeo MVS hardware, opting for Atomiswave instead. While it expands the character roster, the overall feel lacks the excitement of its predecessors. The graphical dissonance between the backgrounds and foregrounds can be jarring, making it a less satisfying addition to the series.
7. Metal Slug 2nd Mission

Unlike its predecessor, Metal Slug 2nd Mission takes a leap forward, offering more expansive levels, better weapon control, and a branching campaign. The challenge ramps up, and it manages to hold onto the fast-paced action that fans love. If you thought 1st Mission struggled, 2nd Mission proves there’s more to explore and enjoy on SNK’s handheld.
6. Metal Slug Tactics

Adapting Metal Slug’s frenetic run-and-gun style into turn-based strategy is no small feat. Yet, Metal Slug Tactics manages to shine through by emphasizing teamwork over individual character strengths. The roguelite progression system offers varied gameplay, but it may not resonate with everyone. Still, it stands out ahead of many of its post-Nazca counterparts.
5. Metal Slug 5

Among the titles released after SNK’s fall, Metal Slug 5 proves to be one of the better entries. Memorable moments, like aerial combat and high-octane vehicular battles, enhance the experience. However, gameplay tweaks like the ground slide mechanic can confuse long-time fans. Despite its flaws, it feels like a step forward compared to Metal Slug 4.
4. Metal Slug 3

Many consider Metal Slug 3 a masterpiece, and while it’s a classic, its lengthy finale can feel more tedious than thrilling. The introduction of bizarre enemies and eclectic missions showcases the franchise’s creativity, but the drawn-out ending may leave some players wanting a tighter conclusion. Nevertheless, the journey leading up to the finale is filled with memorable moments.
3. Metal Slug 2

Metal Slug 2 is often celebrated for its innovative features and character enhancements. However, the infamous slowdown during intense moments can hinder the experience. Despite its shortcomings, it introduced beloved characters and was pivotal in shaping the franchise. The balance of chaos and grounded gameplay makes it a favorite for many.
2. Metal Slug

The original Metal Slug remains a beloved classic that many players revisit. Its simplicity, paired with engaging gameplay, underscores its enduring appeal. With iconic characters, a tight control scheme, and stunning pixel art, it set the standard for everything that followed. It’s a game that combines nostalgia with a genuine sense of achievement.
1. Metal Slug X

Metal Slug X stands as a definitive edition of the series. While it builds upon Metal Slug 2, it addresses previous issues, like slowdown, and enhances the gameplay experience with revamped levels and boss encounters. It’s the ultimate expression of what Metal Slug is about and is often considered the pinnacle of the franchise.
In summary
The Metal Slug series is a remarkable journey through gaming history, showcasing a blend of creativity, nostalgia, and engaging gameplay. Whether you’re a seasoned player or a newcomer, there’s a title for everyone in this dynamic franchise.
Conclusion
The Metal Slug series has earned its place in gaming history, not just for its engaging gameplay but also for its charming art style and unforgettable characters. Whether you’re revisiting old favorites or diving into new entries, there’s always something exciting to explore in the world of Metal Slug.
