Halo 3: ODST is a first-person shooter video game, developed by Bungie and published by Microsoft. It was released on the Xbox 360 video game console exclusively on September 22, 2009, nearly two years after the initial release of Halo 3. Players assume the roles of elite human United Nations Space Command soldiers known as Orbital Drop Shock Troopers (ODSTs) during the events of Halo 2 and Halo 3. After the alliance of alien races known as the Covenant attack Earth, the player explores the ruined city of New Mombasa to discover what happened to their missing teammates, separated from each other as they entered the city. Instead of featuring recognizable characters such as the Master Chief from previous games, the developers focused on the ODSTs.
