Community Supported & Player-Driven Development
Since 2003, Free Infantry has been expanding what Infantry Online is capable of. We strive to enable players and content designers to create zones and game modes that they want to play. A number of features within the game – pioneered by our small community – have found their way into the official servers. With Sony Online Entertainment shutting the servers down in 2012, Free Infantry has brought the community back together in full. Today, we finance, maintain and grow Infantry Online into a bigger and better game.
To this end, Free Infantry has open-sourced the entire server infrastructure required to host the zones, and provides all the tooling that you require to build your own zones.
