playRA

OpenRA's Red Alert in your browser: the real-time strategy classic, one link away. It's crossplay: if you play in the browser, you join the same matches as the people who have the game installed on their computers.

OpenRA is an open source community project that recreates the Westwood strategy classics. playRA takes OpenRA's Red Alert to the browser without changing the game: the rules and the maps are OpenRA's own.

That's why it joins the same public OpenRA servers that show up for people playing on their computers, so browser and desktop players end up in the same match.

The first time you open it, your browser downloads the game files and keeps them along with your settings. From then on, the game opens without downloading everything again.
