What it recreates
Vanguard is an independent browser RTS engine built for Red Alert 2 and Yuri’s Revenge data, currently focused on Soviet single-player skirmishes.
What’s different
The engine runs in the browser and separates Classic mode, which uses original game data, from Original mode, which uses repository-authored assets. AI contributes to development and some assets.
What you can use today
This is a development slice with no formal release, requiring Node.js 20.19+ and a local development server. Classic mode needs lawfully obtained RA2/YR files; Original mode needs no original game. Allied forces, netplay and Yuri gameplay are not complete, so this is not a full Red Alert 2 recreation.
