Metal Slug X Unblocked: Play Neo Geo Arcade Classic in Your Browser

The Unrivaled Legacy of SNK's Neo Geo MVS Masterpiece

In the golden pantheon of 1990s arcade gaming, few titles match the sheer kinetic adrenaline, artistic brilliance, and auditory grandeur of SNK's Metal Slug franchise. Developed by Nazca Corporation (a squad of former Irem software veterans who previously crafted GunForce and In the Hunt) and released on SNK's legendary Neo Geo MVS (Multi Video System) hardware, Metal Slug elevated the side-scrolling run-and-gun genre into an unforgettable sensory extravaganza.

Released in 1999 as an enhanced, re-engineered iteration of Metal Slug 2, Metal Slug X resolved the severe sprite slowdown issues of its predecessor while remixing enemy placements, introducing devastating alternate weaponry, modifying musical arrangements, and shifting daytime stages into moody twilight and midnight environments. Its hand-drawn 2D pixel art animations—boasting fluidly articulated dieselpunk tanks, sprawling multi-tier bosses, comical death animations, and vibrant environmental destruction—remain unmatched even by modern high-budget 2D indie titles.

On SchoolBros, we have preserved Metal Slug X using our high-performance WebAssembly Neo Geo arcade emulator. You can launch Metal Slug X Unblocked instantly on school Chromebooks, library PCs, and home computers with full 60 FPS performance, authentic stereo sound effects, unlimited virtual quarters, and full two-player simultaneous co-op action.

The Roster: Marco, Tarma, Fio & Eri Mechanical Breakdown

Metal Slug X features four iconic playable commandos belonging to the Peregrine Falcon Strike Force and S.P.A.R.R.O.W.S. special intelligence division. While their base movement speeds and jump physics are identical in Metal Slug X, their visual personalities and voice lines bring distinct flavor to the battlefield:

• Marco Rossi (Peregrine Falcon 1st Squad Major): The de facto leader of the team and a brilliant computer programmer. Marco's determined sprint and iconic headband make him the quintessential action hero.
• Tarma Roving (Captain): Marco's cynical best friend and motorcycle engineering savant. Recognizable by his cool sunglasses and blonde pompadour, Tarma's custom animations include playfully inspecting his service sidearm during idle frames.
• Fio Germi (Master Sergeant): The wealthy Italian heiress who enlisted in S.P.A.R.R.O.W.S. Known for her signature glasses, beret, and endearing enthusiastic victory salutes, Fio remains a fan favorite across the globe.
• Eri Kasamoto (Staff Sergeant): An orphaned street survivalist turned elite demolition expert. Armed with high-explosive ordnance and razor-sharp reflexes, Eri's combat animations exude tactical precision.

Mission-by-Mission Combat Walkthrough (Missions 1 through 6)

Surviving the relentless bullet-hell warfare of Metal Slug X requires memorizing enemy spawn patterns, prioritizing lethal anti-air vehicles, and conserving heavy ammunition for grueling multi-phase boss encounters:

Mission 1 (Arabian Desert Ruins): Fight through insurgent riflemen and suicide bombers riding atop armored dromedaries. Master close-quarters combat knife slashes to conserve pistol bullets. Watch for falling minarets and subterranean scorpions. The stage culminates against The Iron Nokana prototype ironclad airship, requiring you to destroy its bottom-mounted flame turrets before detonating its main turbine engines.

Mission 2 (The Cursed Pharaoh Tomb): A terrifying descent into ancient Egyptian catacombs populated by flesh-eating scarab beetles, leaping mummy mages, and spiked ceiling crushers. Beware of purple mummy mist: inhaling this noxious cloud transforms your soldier into a shambling mummy with halved movement speed! Destroy the dual stone pharaoh statues and climb the collapsing stone pillars to escape the grinding mechanized jaw boss Aeshi Nero.

Mission 3 (Freight Train & Air Convoy): Jump across speeding military flatbed train cars while dodging relentless mortar fire from overhead gunships. Commandeer the SV-001 Metal Slug Tank to blast through barricades and shoot down flying stealth bombers. The mission concludes atop a moving freight car against Dragon Nosuke, an enormous tracked fortress equipped with a heavy hydraulic ram and incendiary rail cannons.

Mission 4 (Hong Kong Neon City Streetfight): Navigate dense urban markets filled with civilian food stalls, street vendors, and patrolling Rebel armor. Feasting on roasted turkeys and bakery pastries triggers the hilarious Fat Transformation, turning your commando into a rotund juggernaut with expanded bullet spreads and increased bomb blast radii! Battle through the subway tunnels to annihilate Big Shiee, an amphibious dreadnought battleship operating inside flooded city canals.

Mission 5 (Subterranean Bio-Weapons Laboratory): Delve into an underground sewer network teeming with mutated flesh-eating subterranean mutants that vomit acidic projectile arcs. Rescuing lab prisoners yields experimental Laser Guns and Super Grenades. The final sector pits you against Hozmi, an enormous mechanized nuclear submarine trapped inside a massive subterranean subterranean basin.

Mission 6 (Arctic Fortress & Alien Mothership Invasion): The apocalyptic grand finale. Fight through freezing Siberian tundras against General Morden's elite guard, followed by an unprecedented narrative twist: an alien armada (The Mars People) betrays Morden! Team up with your former human enemies to battle through waves of grey extraterrestrial saucers, telekinetic squid-aliens, and the gargantuan city-sized orbital mothership Rugname in an epic climax of 2D bullet-hell combat!

Close-Quarters Combat & The 100-Point Knife Slash Technique

A fundamental secret separating casual coin-feeders from master Metal Slug players is Close-Quarters Combat (CQC). When your soldier approaches within one sprite tile of an enemy human soldier, pressing the fire button will not discharge a firearm. Instead, your soldier executes a lightning-fast combat knife slash (or martial arts punch for Fio):

• Instant One-Hit Elimination: The knife slash bypasses enemy armor and eliminates standard Rebel soldiers in a single frame.
• Scoring Multiplier: Killing an enemy with the knife awards 500 bonus points compared to the modest 100 points granted by a standard bullet kill. For high-score competitive runs on SchoolBros, mastering the knife dash through crowds of soldiers is the primary method for topping leaderboard scores.
• Item Drops: Knife kills have an elevated probability of forcing soldiers to drop food bonuses or coin bags.

The Hilarious Status Transformations: Mummy and Fat Modes

Metal Slug X introduced unique status transformations that radically alter your soldier's physical attributes:

Mummy Mode: Triggered by inhaling the toxic breath of Egyptian mummies or purple bat vapor in Mission 2. Your character turns into a white-bandaged zombie. In this state, your sprint speed is reduced by 60%, jumping height is severely degraded, and your grenade throwing animation takes nearly two full seconds. Furthermore, taking any damage while in Mummy form instantly dissolves your soldier into dust! The only cure is finding a hidden Holy Water potion bottle dropped by rescued prisoners.

Fat Mode (Overweight Commando): Triggered by collecting more than 16 food items (meat, chicken, bread, apples) without dying. Your commando expands into a rotund, lovable tank. Paradoxically, Fat Mode is an enormous combat buff! Your basic pistol bullets become giant bouncing cannonballs with wider hitboxes, your shotgun blasts cover 50% more vertical screen space, and your grenades detonate into massive incendiary mushroom clouds. The transformation wears off after 30 seconds or upon picking up a Diet Vitamin pill.

Mastering the SV-001 Metal Slug Tank and Heavy Vehicles

The iconic titular vehicle—the SV-001 Metal Slug—is the pinnacle of arcade combat satisfaction. Equipped with dual 12.7mm Vulcan cannons that rotate a full 360 degrees and a 127mm low-pressure main rifled cannon, the Metal Slug can jump, duck, and crush infantry under its reinforced caterpillar treads.

Crucially, the tank features an Invincibility Egress Maneuver (The Slug Hop). Pressing Down + Jump ejects your soldier out of the hatch. During the two-second ejection and re-entry animation, both your soldier and the vehicle are completely invulnerable to enemy projectiles! Skilled players continuously hop in and out of the tank to phase through lethal boss screen-clearing laser blasts.

Slug Vehicles Roster and Special Abilities

Vehicle Name	Mission Appears	Main Armament	Secondary Cannon	Mobility Trait
SV-001 Metal Slug	Missions 1, 3, 6	Dual Vulcan 12.7mm	127mm AP Shell	Hydraulic jumping, crouching, tread crush
Camel Slug	Mission 1	Mounted Dual Vulcan	Standard Hand Grenades	High vantage point, vulnerable to direct fire
Slug Flyer	Mission 3	Air-to-Air Vulcan	Air-to-Ground Rockets	Full 360-degree aerial flight maneuvering
Black Hound Slug	Mission 5 (Secret)	Twin Vulcan & Laser	Armor-Piercing Mortar	Enhanced Rebel prototype with high armor

Rescuing POWs and Secret Item Spawns

Prisoners of War (POWs) are tied up throughout every stage. Cutting their ropes with your knife or shooting them frees them. Rescued prisoners dig into their boxer shorts to reward you with heavy weaponry, bomb crates, or high-value treasures (such as 30,000-point diamond rings or 10,000-point gold bars). Rescuing the legendary martial artist prisoner Hyakutaro Ichimonji allows him to fight alongside you, firing lethal Hadoken-style energy fireballs at enemy tanks!
