Orbit the edge of the screen with your gun aimed at the core while waves of enemies spiral out toward you, keep moving, keep firing.
You ride the rim of a circular arena, always shooting toward the middle. Enemies emerge from the center and spin outward along the spiral; clear them before they reach your ring. Stay alive as long as you can and push your score higher.
Spiral Storm recreates Gyruss, released by Konami in 1983 and designed by Yoshiki Okamoto, which took the fixed shooter and bent it into a circle.
You fly around the rim of the screen rather than along its base, firing inward while enemies spiral out of the centre toward you. Because there is no floor, there is no safe corner — every position is equally exposed and the only defence is movement. The frame is a journey from Neptune to Earth, a planet per stage, set to an electronic arrangement of Bach's Toccata and Fugue in D minor that most players remember better than the game.
Spiral Storm is an original free browser arcade shooter built around a single circular play space, a fresh spin on classic rim-defence blasting. Just open and play.
