"Dust II", also known by its filename de_dust2, is a video game map featured in the first-person shooter series Counter-Strike. Dust II is the successor to "Dust", another Counter-Strike map, and was developed by David Johnston prior to the official release of the original Counter-Strike game. It was designed with the aims of simplicity and balance, based on its symmetrical design and two equidistant points, for which the two teams must fight over for control. The map was first released in March 2001 for the original Counter-Strike game and is present in all games in the series. Apart from graphical updates, it underwent minimal changes after its initial release, before receiving a major revision in Counter-Strike: Global Offensive in October 2017. The map has been popular with players since its initial release, and both its original and revised design in Global Offensive have been positively received by players and mapmakers.
