What is Counter Strike: Condition Zero?

Counter-Strike: Condition Zero (abbreviated CS: CZ or just CZ) is the single player version of the multiplayer game, Counter-Strike. The game was released in 2004 using the aging GoldSrc Half-Life engine. CS: CZ also features a multiplayer mode, which mostly features updated character models, textures, maps and other graphical tweaks.

It is very similar to Counter-Strike 1.6, featuring nearly identical gameplay, weapons, equipment, and maps popular in the multiplayer version. The textures are all different, as are the guns and maps. Nightvision makes a whirring, whining noise and in some servers casts an eerie glow around the player when in use. Also, players drop their grenades when they die, allowing other players to take them. CZ offers a new bot system in which the player can "create" computer players of varying skill levels and control the weapons they use to practice. In the single-player campaign, the player leads a hand-picked squad of counter-terrorists through missions around the world thwarting terrorists. The single-player mode is often praised for the highly intelligent AI, which are made to emulate actual players.

Some items introduced in Counter-Strike 1.6 were to be originally introduced to Condition Zero, such as the FAMAS, IMI Galil and the Tactical Shield. New player models were introduced, one for each side. Spetsnaz, the Russian security force for Counter-Terrorists, and Midwest Militia, a supposedly U.S. based group of dissidents for the terrorists. The second update of CZ feature the new hostage AI, which apparently gives the hostages emotions. They'll escape on their own if left unguarded, panic if firefight is heard, "talk" to terrorists and counter-terrorists, and navigate the entire map by using ladders, etc.
