The original Counter-Strike 1.6 release included a total of 25 maps, which were divided into two categories: Bomb Defusal and Hostage Rescue. The Bomb Defusal maps included Aztec, Dust, Dust2, Inferno, Nuke, and Train. The Hostage Rescue maps included Assault, Chateau, Italy, Militia, Office, and Siege. Additionally, the game also had a few other maps that were not part of either category, such as 747 and Dust Devil.
