Your hands each have their own job here. In Radius Raid unblocked the keyboard moves your little ship while the mouse points the gun, and the arena is larger than your screen, so enemies keep sneaking in from the edges.

How to play Radius Raid
Press Play and your ship appears in the middle. It always turns to face your pointer, and holding the left mouse button sprays shots in that direction. Move with the keys to dodge.
Enemies do not shoot. They hurt you only by touching your ship, and your health bar drains the longer they stay in contact. When it empties, the round ends with a summary of your score, kills and time.
Every kill fills the progress bar at the top. A full bar bumps you to the next level and adds a new kind of enemy, like ones that split apart, ones that are hard to see and ones that release swarms. Once all types are in, enemies just get tougher.

Tips
- Keep moving in wide loops. Standing still lets enemies pile up on you. Circling the arena keeps most of them in front.
- Switch on autofire. Pressing F makes the ship shoot nonstop, so your only jobs are steering and aiming.
- Kill splitters at range. Their pieces scatter when they burst, so do not pop them right next to you.
- Prioritize spawners. An enemy that keeps releasing small chasers gets worse the longer it lives.
- Use the space. The arena is twice your screen size. Fly away from a crowd and pick it off as it follows.
Radius Raid questions
Why did Radius Raid pause on its own?
It stops whenever the game loses focus, for example after a click on another part of the page. Press P or the Resume button to keep playing.
Does it work on a phone or tablet?
No. There are no touch controls, and you need both a keyboard and a mouse pointer. A laptop or Chromebook with a mouse is best.
Does the autofire setting stick?
Yes. The game remembers whether autofire was on the next time you play.
