Why you might like it

  • A Cartoon Network-licensed MMO that let players fight alongside dozens of iconic CN characters (Ben 10, Dexter, the Powerpuff Girls, and more) against an alien invasion — a genuinely ambitious crossover for its 2009 launch.
  • The fan project OpenFusion is an actively maintained, open-source reverse-engineered server that runs public servers today, recreating multiple versions of the game across its lifetime including the original 'Future' build and the later 'Academy' tutorial revamp.
  • A dedicated community, including groups like Sunrise Games (who also run Toontown private servers), continues to operate and improve on OpenFusion-based servers as of recent years.
Before you play

Things to consider

  • The official game shut down permanently on August 29, 2013. A subsequent unofficial revival, FusionFall Universe (Retro + Legacy), ran openly with apparent informal tolerance for years but was hit with a Cartoon Network DMCA takedown on April 16, 2020, forcing Retro offline and cancelling Legacy entirely.
  • The current OpenFusion project operates with more legal caution as a bare server emulator rather than a full licensed-content revival — Cartoon Network's willingness to tolerate any given fan project has proven unpredictable, as the 2020 takedown showed.
  • Because OpenFusion supports several different historical game builds, expect some instability, missing/incomplete content on certain builds, and occasional crashes, particularly on the more experimental 'Academy' version.
