Vertigo

Vertigo is a bomb defusal map featured in Counter-Strike and later added to Counter-Strike: Global Offensive with the October 1st, 2012 update

Vertigo is based on a skyscraper that was under construction and centered the conflict between the Counter-Terrorist and the Terrorist teams. The main objective for the Terrorists were to bomb the building while the CTs must prevent them from achieving their goal.

Official description:

Terrorists are trying to bomb Rizzleton tower before it reaches completion.

Counter-Terrorists: Prevent the building from being destroyed.

Terrorists: Plant the bomb and blow up the building.

Other Notes: Don't fall off.
