Originally known as the "Dogfighting Module", Arena Commander is a stage of Star Citizen development that was released to the community on June 4, 2014. It was previously expected to be released in the late May 2014. In this mode, players can fight against each other and AI in a deathmatch-style combat system.
On May 16, 2014, Chris Roberts announced that Arena Commander was expected to be released around May 29, 2014, based on a best possible projection.

According to in-game lore, Arena Commander was developed by Original Systems. It can be accessed through Electronic Access on main menu.
