Once the bomb has been planted, the counter-terrorists must locate and defuse it in 45 seconds (this is a variable it can be changed commonly also set to 35 seconds depending on the server admin(s)) before it explodes. If the terrorist carrying the bomb is killed, his team members will have to locate it using their radar and can pick it up like a dropped weapon.
One of the terrorists starts out with a C4 explosive that can only be planted at bomb sites usually there are two bomb sites on the map, defined by A and B, one of which is sometimes near the counter-terrorist spawn.
That was pretty funny, since you can take cs_militia hostages to the toilets :). In older version of Counter-Srike, Terrorists could also "use" the hostages, and led them to an other location. Killing the entire enemy team also ends the round, but results in less money gained for the next round. If a player on either team kills a hostage, accidentally or intentionally, they lose money and may also be kicked off the server (depending on the server's configuration).
If the Counter-Terrorists rescue all of the hostages within the time-limit, they win the round. The Counter-Terrorists must lead them from their location to a rescue zone, typically located around the Counter-Terrorists' spawn. Four or more computer-controlled hostages are strategically located at or nearby the Terrorist spawn. Hostage Rescue (cs_) maps are the original map-type, based on a hostage rescue situation.
