Office is a hostage rescue map that has been included in each successive version of Counter-Strike. Valve made graphical improvements and updated the map in order to keep it playable in each new version. It is currently a Reserve map in CS:GO's official matchmaking. The map is set in an office building during winter, where Terrorists have taken over the building with hostages inside. The Counter-Terrorists must make their way into the building from the parking garage and rescue the hostages or take out the Terrorists without incurring collateral damage.
