Play Dr. Micro Online

Dr. Micro is a 1983 arcade game from Sanritsu, a lesser known but prolific developer of the era. It arrived during the peak of maze chasers and single screen action games, offering a twist on the formula by shrinking the player down to microscopic scale. The cabinet was not particularly common, but those who found it often remembered its strange, biological theme.

You control a small, white coated scientist navigating a grid of interconnected cells. Your goal is to clear each screen of all enemy microbes by either avoiding them until a power up appears or by collecting a syringe that temporarily lets you hunt them. The purple microbes are especially dangerous; they move in unpredictable patterns and often corner you if you hesitate. Each stage feels like a tense puzzle, demanding quick decisions and careful route planning. It is a game of sudden reversals, where a moment of vulnerability can instantly become a frantic chase.
