  • 2003 - Senile Team releases Beats of Rage, a free beat-'em-up for DOS inspired by SEGA's Streets of Rage series using assets from SNK Playmore's King of Fighters series. The game quickly achieves mass popularity through word of mouth. Senile Team releases an edit pack allowing anyone interested to create a module for the BOR engine.

  • 2005 - Developer Kirby2000 asks Senile Team to open the source code to BOR. They agreed, and the project is named OpenBOR. The project quickly spawns numerous ports and branches, each with unique features.

  • 2006 - Developer Sumo1X (SX) reorganizes the loose coalition of developers into what is now known as the OpenBOR Team. Features from the various branches are backported into the original OpenBOR.

  • 2011 - Sumo1X retires from the OpenBOR Team, and hands management duties to DCurrent (Damon Caskey).

  • 2017 - OpenBOR repository migrates from SourceForge to Github.

  • 2021 - Development continues on OpenBOR 4.0, with various internal source cleanups, a more object centric script engine, and fixes for long standing issues.

  • 2024 - After an extended development cycle, the first official 4.0 build drops. Development continues to refine and fill requests that did not make the initial 4.0 release deadline.
