A web server has been developed to enable offline multiplayer for Age of Empires games, allowing players to host and join games without an internet connection. The server supports Age of Empires 1, 2, and 3 Definitive Edition, as well as Age of Empires IV: Anniversary Edition and Age of Mythology: Retold. The project aims to future-proof the games and ensure continued multiplayer functionality even if official servers are shut down. The server and launcher are available for download and can be used to host and join games.
