Original copies of Counter-Strike: Global Offensive's Aztec, Shorttrain, Dust, and Office maps compatible with the game's four "unattainable" achievements.
Historically, these maps were hosted by the official CSGO development Steam Workshop account, but have since been removed. With their removal, several CSGO achievements became unattainable.
Navigate to the CSGO directory inside the Steam install directory:
steam\steamapps\common\Counter-Strike Global Offensive\csgo\maps
Once there, rename the current, valid bsp files (example: cs_office.bsp) to something else if you don't want to reverify your game files, and drop all four maps into the folder. Once in-game, launch the maps through the console command as follows:
map $mapname
For example:
map cs_office
Fulfill achievement criteria and the achievement should pop. Office is the easiest map to test, requiring the player to break a certain number of windows in a single round. Other maps will require adjustments to cfg files for the required gamemodes to load properly.
