There is another single-player mission pack called Deleted Scenes. These requirements include objectives 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. It is bundled with a copy of Counter-Strike regardless of how you purchase it. Condition Zero features a multiplayer mode, which features updated character models, textures, maps, and other graphical tweaks. The game was released in 2004 via both retail stores and Steam and uses the GoldSrc engine. Counter-Strike: Condition Zero ( CS: CZ) is a first-person shooter video game and the sequel to the original Counter-Strike.
