Play Tekkyu Fight! : The Great Battle Gaiden Online

Irem released Tekkyu Fight! The Great Battle Gaiden for the Game Boy in 1992. It was part of that wave of early 90s portable games, straightforward action titles you could pick up and play in short bursts. This one is a side story to the Great Battle series, which often mashed up characters from different Irem and other company licenses, though this particular entry feels more self-contained.

You control a small robot navigating single-screen rooms, clearing them of all enemies to proceed. Your main goal is to fight through these stages, using a basic sword attack for close combat. The key mechanic is a charge shot for your sword, which lets you fire a projectile after holding the attack button, essential for hitting distant foes. You also collect power-ups that change your weapon, like a spread shot or a more powerful beam. The game moves at a quick pace, and the difficulty comes from enemy patterns and the limited space in each room. It feels like a compact, energetic brawler where you are constantly moving and reacting.
