Raiden Storm is a free, browser-based vertical scrolling shoot 'em up (shmup) inspired by the classic Raiden arcade series. Pilot your fighter through 6 increasingly challenging sectors, take down epic bosses, upgrade your weapons by collecting power-ups, and chain combos for high scores. No download, no signup - just instant arcade action.
Use WASD or Arrow Keys to move your ship, or hold a mouse / touch to drag it. Press SPACE to launch a screen-clearing bomb and P to pause. Collect the P power-up to level up your main weapon, and grab rare items like the Nuke (N) or Super Shield (X) for emergencies.
