Operation C
C号行动
Operation C is a 1991 Game Boy action platformer by Konami. You control a soldier fighting through multiple stages filled with enemies. The game uses a side-scrolling run-and-gun format: D-pad moves you left and right, buttons handle jumping and shooting. Stages vary in enemy placement and layout, requiring tactical weapon selection to proceed. You collect power-ups that grant new weapons—spread shot, rapid fire, and others—with each offering different attack patterns. Difficulty escalates as you progress, with stages featuring tighter enemy patterns and longer encounters. The game limits your number of continues, making each stage attempt meaningful. Success depends on mastering weapon switching and precise timing to clear the escalating challenges.
