About This Game
What Is Radius Raid
Radius Raid is an adrenaline-fueled retro space arcade shooter created by developer Jack Rugile for the famous js13kGames competition. Designed to deliver maximum arcade intensity within a micro-code footprint, Radius Raid drops you into a glowing neon arena where relentless swarms of geometric enemies attack from every angle.
Reminiscent of classic twin-stick shooters like Geometry Wars and Asteroids, Radius Raid challenges your reflexes, positional awareness, and target prioritization. With crisp particle effects, dynamic sound synthesis, and endless wave scaling, it offers instant browser-based arcade action with zero load times or installation required.
How to Play Radius Raid
In Radius Raid, you control an agile starfighter in an open multidirectional arena. Enemies spawn along the perimeters of the screen and converge rapidly on your position.
- Ship Movement: Use WASD or the Arrow Keys to navigate through space and dodge incoming enemy waves.
- Aiming & Shooting: Move the Mouse to rotate your aim in 360 degrees, and hold the Left Mouse Button to fire your primary laser.
- Autofire Toggle: Press F to toggle automatic continuous firing, allowing you to focus completely on evasive maneuvers.
- Game Controls: Press P to pause the game, and M to toggle audio on or off.
Destroying incoming enemies grants score points and occasionally spawns floating power-ups. With 13 distinct enemy types featuring unique movement speeds and tracking behaviors, staying mobile and keeping the screen clear is the only way to survive.

- Instant Browser Play: Lightweight HTML5 design means instant loading and smooth 60 FPS performance on modern browsers like Chrome and Firefox without downloads or sign-ups.
Tips & Strategies
- Master Orbital Movement: Never stand still or back up blindly. Circle around the outer perimeter of enemy clusters in a continuous orbital pattern to maintain open escape routes.
- Activate Autofire (
F): Toggling autofire frees your hands from holding down the mouse button, letting you dedicate 100% of your attention to dodging incoming projectiles and enemy collisions. - Don’t Risk Your Ship for Power-Ups: Floating power-ups are tempting, but chasing a boost into a dense cluster of enemies often leads to immediate destruction. Wait for a clear path before collecting them.
- Prioritize Fast Chasers First: Target quick-tracking enemies that close the distance rapidly before dealing with slower, bulkier geometric shapes.
- Manage Screen Space: Avoid getting pinned against the screen boundary. Keep your ship toward the open center or middle-ring area so you can react to perimeter spawns in any direction.
