Daiku No Gensan (widely known outside Japan as Hammerin' Harry) is a classic 1990 arcade platformer developed by Irem. In this releaseโrunning on the original M82 arcade hardwareโyou control Gen, a spirited carpenter whose home was unjustly demolished by the corrupt Kuroki-gumi construction company. Seeking revenge, you take up your massive wooden mallet to smash through waves of hostile builders and heavy machinery across multiple vibrant stages.
How to Play
The objective is to fight your way to the end of each level and defeat the boss of the corrupt construction crew. As an arcade title played in the browser, use the Arrow Keys to move or crouch. Press Z to swing your mallet, and press X to jump. Your hammer is your primary tool for both offense and defense, allowing you to smash enemies and deflect hazards.
Tips
- Defensive Swings: Your mallet can swat away incoming projectiles like flying crates or hardhats, keeping you safe from ranged attacks.
- The Ground Pound: Try jumping and attacking downward to trigger a shockwave that stuns or damages nearby grounded enemies.
- Find the Lunchboxes: Smash open crates and barrels in the environment to find hidden lunchboxes that restore your health.
