Mirage was originally known as de_cpl_strike before being renamed Mirage.
The map was created by Michael Hüll and first appeared in the competitive Counter-Strike mapping scene under the name de_cpl_strike. Valve later adapted it for Counter-Strike: Global Offensive and released it under the name Mirage.
Mirage is a bomb-defusal map with two sites, a central mid area, and routes connecting the Terrorist spawn to apartments, palace, and the bombsites. Its layout supports both rapid attacks and slower mid control.
The map is sometimes confused with de_cpl_strike’s earlier competitive identity or with Cache because both became important tournament maps. They are separate maps, and Mirage’s earlier name specifically refers to de_cpl_strike.
