Asteroids
A multiplayer Asteroids arena. Blast drifting rocks, dodge rival ships and climb the live leaderboard, straight in the browser.
About
Open the site and you drop straight into a shared game filling the window: a 50-player, wrap-around arena larger than the screen. Aim your ship with the mouse or by touch, hold to thrust, and fire automatically at rocks that split as you hit them.
The arena is never empty. The server pads it with up to 20 bots that fly like players, and they thin out as real pilots arrive, reaching zero once twenty people are playing.
Features
Gamehoster
The realtime game server runs on Gamehoster, at game.asteroids.net.
Sharp on any screen
The canvas follows the window size and the device's pixel ratio, so the picture stays crisp on high-resolution displays.
No sign-up
Arrive, play, and share your score.
Never empty
Up to 20 bots fly like players and make way as real pilots arrive, so there's always someone to fight.
Minimap and leaderboard
The whole wrap-around field in the corner, with the top scores beneath it.
Mouse or touch
Aim with the mouse or a finger and hold to thrust; firing is automatic.
