There is another single player portion consisting of eighteen missions called 'Deleted Scenes' made by Ritual Entertainment.
These requirements include targets such as 'kill 3 enemies with a Clarion 5.56' or 'win a round in 45 seconds'. Unlike other Counter-Strike games, Condition Zero also contains a single-player mission pack with the player unlocking maps and more efficient bots as they pass certain requirements for each map while playing as a Counter-Terrorist.
Condition Zero features a multiplayer mode, which features updated character models, textures, maps, and other graphical tweaks.
The game was released in 2004 using the GoldSrc Half-Life engine.
