At first, FusionFall Legacy was a Recreation of the original game with some improvements, it was not until FusionFall Retro came to be and Legacy's main concept changed to be a fully Reimagined version of FusionFall, based on concepts and ideas that the original team wasn't able to fully realize at the time.
Before April 16th, 2020, FusionFall Legacy was still in development. However, due to the DMCA takedown request by Cartoon Network, FusionFall Legacy has been cancelled.
- Before the DMCA takedown, the FFU team were planning to change the games name to "FusionFall Worlds Collide", naming the game after the manga that served as a prolouge to the original game.
