Achtung Royale is a free multiplayer browser game based on the 1995 DOS game Achtung, die Kurve! Each player steers a worm using only two keys, left and right. The worm trail grows behind them, and touching a wall or any trail ends their round; the last player alive wins.
The game adds online play for up to 30 players, a drop-in Play Now mode, a 30-player knock-out Royale held every half hour, ranked 1 vs 1 and free-for-all ladders, private game rooms, 13 power-ups and local play for up to 10 players on one keyboard. It runs in the browser for both PC and phone. Play and App store apps are in development.
