For Games for Windows - LIVE on Windows 8 or later, install the latest Games for Windows - LIVE software.

Universe at War: Earth Assault is a singleplayer and multiplayer bird's-eye view RTS game.

The game received three official patches and a free map pack post-release.

While the game was delisted from digital stores for unknown reasons, it remains mostly stable on modern systems, and its Games for Windows - LIVE multiplayer service is still online as of 2023. However, the DirectX 10 setting was never optimized, and causes a performance hit until reverted to DirectX 9.0c in the game's settings.
