Advance Wars by Web (2004)

Advance Wars by Web (aka. AWBW) is an unofficial site created by Aaron Marriner in 2004 that allows people to play Advance Wars multiplayer online in a web browser. AWBW is primarily based upon Advance Wars 2: Black Hole Rising with select gameplay elements added in from Advance Wars 1 and Advance Wars: Dual Strike, but also expands upon the vanilla experience by including a wider selection of COs than any previous game in the series, up to 16 players per match, additional content and quality-of-life (and some bugs and glitches here and there) and a broad array of community-focused features such as custom maps, spectator controls, replays and a ranked matchmaking system.
