Metal Slug Advance (Japan)

Released in 2004 for the Game Boy Advance by SNK Playmore, Metal Slug Advance (Japan) is the first mainline entry of the iconic Metal Slug run-and-gun shooter franchise to launch exclusively for Nintendo’s handheld console. This Japanese original release brings all the chaotic, over-the-top action the series is famous for, optimized perfectly for GBA’s portable hardware. You play as one of two new recruits from the Peregrine Falcon squad: Walter Ryan, a sharp-shooting young soldier, and Nadia Cassel, a trained combat specialist, tasked with taking down General Morden’s rebelling forces on a remote island base. Unlike earlier home ports of older Metal Slug games, Metal Slug Advance was built from the ground up for GBA, packing vibrant 32-bit pixel art that retains the series’ signature cartoonish, exaggerated style – from massive exploding enemies to towering end-level bosses that fill the entire GBA screen. The title also introduces a unique collectible card system, where you unlock ca

Game Guide

Whether you’re a long-time Metal Slug fan or new to this GBA exclusive, these tips will help you survive General Morden’s army and unlock all of the game’s hidden content. First, master the core GBA controls: use the D-pad to move, A for primary fire, B to jump, and the L shoulder button to throw explosives. Always keep moving – standing still makes you an easy target for enemy snipers and long-range artillery, which is one of the most common mistakes new players make. The game’s unique card system is your biggest asset: every enemy has a chance to drop a unique card when defeated, and you can equip up to three cards at a time for permanent passive bonuses. Early in your playthrough, prioritize equipping cards that increase your maximum health and extend your weapon’s magazine size – these buffs make every encounter much easier, especially in the harder late-game levels. Look out for breakable walls and structures throughout every stage: almost every level has at least one hidden secret path that leads to rare cards, extra lives, and powerful secret weapons like the laser rifle or rocket launcher that make boss fights far more manageable. When you face a boss, always save your heavy ammo and explosives for its marked weak point – almost all bosses have a visible glowing core or cockpit that takes 2-3 times more damage than other armored parts. For example, the first stage’s giant armored train boss has a clear weak point on its front cannon, so focus all your fire there instead of wasting ammo on its protected sides. If you get access to a Metal Slug tank, don’t waste its health on low-level groups of regular soldiers. Save the tank’s durability and heavy firepower for the end-of-level boss, as its cannon will cut through a boss’s health bar much faster than your standard weapons. The original Japanese release has a slightly more forgiving default difficulty than the western international release, but you should still check every breakable crate for hidden food item
