Radius Raid

Radius Raid drops you into a small ship at the center of an endless enemy swarm. Move with WASD or the arrow keys while aiming and firing with the mouse, twin-stick style, as 13 different enemy types close in from every direction. Collect one of 5 powerup types to shift the balance in your favor, and lean on autofire when things get too hectic to keep your mouse button held down. Layered parallax starfields scroll behind the action, retro sound effects punctuate every kill, and your best runs are saved locally so you always have a score to beat. It's a tight, score-chasing arcade shooter built for one more run.

Click Play to begin. Move your ship with WASD or the arrow keys while aiming and firing with the mouse. Destroy enemies before they reach you, and collect powerups that drop to boost your ship. Hold F to toggle autofire, P to pause, and M to mute. The run ends when your ship is destroyed; check Stats for your best runs.

Move: WASD or Arrow keys. Aim/Fire: mouse. Autofire: F. Pause: P. Mute: M.
