RadiantGames is a browser-based game launch desk for QuakeWorld multiplayer, the Half-Life: Uplink demo, and Diablo shareware. It brings each game into a player window with step-by-step launch instructions, helping players choose the right session and navigate its menus. Search and filter the available players, or save favorites and view recent launches on a personal shelf without creating a RadiantGames account. The app includes focus and fullscreen options, practical guides for common launch and input issues, and a browser check for local bookmark storage, WebAssembly support, and fullscreen availability. The check does not guarantee that a game will work or test servers and game files. Saved items are launcher links, not game saves; character progress and game data remain with each original project.
