Play Redcoats.io in Your Browser

Redcoats.io background

Redcoats.io is made by Yp3d, an independent developer from the UK who also runs yp3d.com and has made other multiplayer WebGL games such as Ships 3D and Tanks 3D. The game was released in 2026. According to the developer's site, its front end is written in TypeScript with three.js and WebGL2, and newer Yp3d projects use C++ servers.

The official site describes battles with up to 1,000 concurrent players on a single map, set in the era of European line infantry, flintlock muskets and wooden warships. It runs in the browser without installation and is free to play; the developer recommends Chromium-based browsers such as Chrome, Edge or Brave.

How to play Redcoats.io

You join one side of an ongoing war and fight in one of four roles. Musketeers carry a flintlock with a bayonet and are strongest in firing lines; cavalrymen ride horses to flank and scout; cannoneers work field guns that fire round shot at range or grapeshot up close; sailors crew warships off the coast that can bombard land targets or other ships. The war is decided by capturing and holding forts, so sessions revolve around pushing toward objectives with your team.

1. Open the page in a Chromium-based browser and wait for the client to load.
2. Pick a side and a role, then spawn onto the battlefield.
3. Move with WASD, aim with the mouse, shoot with left click, switch weapons with 1-5, and press F to mount, board or use objects.
4. Press M for the map to find forts, and use Shift to aim more precisely.
