Counter-Strike: Condition Zero (CZ or CS:CZ) is a multiplayer video game
and the follow-up to Counter-Strike. The game was released in 2004
using the GoldSrc Half-Life engine. CS:CZ features a multiplayer mode,
which features updated character models, textures, maps and other
graphical tweaks. Unlike other Counter
-Strike games, Condition Zero
also contains a single-player mission pack with the player playing as
counter-terrorist alongside bots. The player unlocks maps and more
effective bot teammates as he or she passes certain requirements for
each map while playing as a counter terrorist. These requirements
include targets such as "kill 3 enemies with a Bullpup" or "win a round
in 60 seconds". Counter-Strike bots are a prominent part of Condition Zero gameplay.
