Rex Ronan: Experimental Surgeon is a fascinating relic of the 16-bit era's "edutainment" push, developed by Raya Systems and funded in part by the American Cancer Society. Players take on the role of the titular surgeon who shrinks down to microscopic size to perform life-saving surgery on Jake, a man dying from tobacco-related illnesses. While the premise is heavily inspired by films like Fantastic Voyage, the execution is a mix of platforming and combat that serves as a direct, if somewhat heavy-handed, anti-smoking PSA.
The gameplay is divided between navigating through Jake’s various internal systems—ranging from the lungs to the brain—and engaging in side-scrolling action. Using tools like the Sonic Resonator and the Laser Scalpel, Rex must clear tar, nicotine, and hostile mutated cells while avoiding the body’s own natural defenses. However, the experience is frequently interrupted by educational trivia questions that test the player's medical knowledge; failing these results in a loss of health, making the pacing feel somewhat disjointed compared to traditional action titles.
Visually, the game utilizes the SNES color palette to create surprisingly detailed, if somewhat grotesque, depictions of human anatomy and the ravages of smoking. While the sprite work is functional, the stiff controls and high difficulty spikes often hinder the enjoyment of the educational message.
