Maps are one of the most important reasons why counter strike 1.6 is so popular. They bring down this charm and the missions and scenarios of the game are directly linked to the map being played. Most modes have specific maps. At first, counter strike 1.6 was designed with just a few basic maps. Then came the avalanche of maps created by the community to make you believe that over 20,000 maps were created.

Maps are classified according to objectives so we have maps in the following categories: Arena, Assassioantion, Bomb Defuse, Combat, Deatmatch, Escape, Fight Yard, Fun Type, Hostage and bomb, Hostage rescue, other maps. Most popular are: DE_( Bomb Defuse), CS_(Hostage Rescue) and FY_(Fight Yard).
