🎮 Play Knightmare Online (Sega Master System)

Knightmare is a 1986 vertical shoot ’em up from Konami for the Sega SG-1000. You control a lone knight moving across the bottom of the screen, firing upward into formations of enemies that scroll down from above. The game rewards pattern recognition — each wave repeats, so reading the shape early is more useful than pure reflex.

How to play

Move left and right with the arrow keys. Press Z (Button A) to fire; X maps to Button B and Enter starts or resets the game. The screen fills quickly — stay mobile and use the full width of the stage to find gaps between formations rather than standing still.
