Office

Office (cs_office), known as The Office Complex in Counter-Strike, is an official hostage rescue map. It has since appeared in every multiplayer Counter-Strike game.

It is set in the winter in a office building with parking areas and outside yards. Counter-Terrorists (CT) spawn zone is in a parking garage while the Terrorists are inside the offices.

Arguably, Office is one of the more balanced Hostage Rescue maps in Counter-Strike as players will have even ground throughout the map and the hostages are easily escorted in the wide pathways.
