Hammerin' Harry (World, M81 hardware) — About this game
Hammerin’ Harry follows a homeowner’s furious response to the demolition of his house. Harry fights the Rusty Nailers with a large hammer, using direct blows against nearby workers or pounding the ground to send shockwaves in both directions. The route passes through construction areas, sewers and a ship before reaching the mansion associated with the demolition order, with boss encounters blocking progress. Timed bonus stages add a different challenge by asking Harry to destroy a required number of enemies. Judge whether a nearby hammer strike or a ground shockwave better covers an approaching group.
