This is a list of the most used console commands in CS:GO and CS2. I use these for practising or making screenshots for my guides.

For a more complete list visit Tobys list of all CS:GO console commands or this page for a list of some very usefull commands for settings you cannot change in the game menu. Also here is a guide of all commands you could use for practicing throwing grenades.

First off all, how to activate the console. Just go in the CS2 main menu, choose „Game Settings“ and set „Developer Console“ to „Enable“. Under „Keys“ you have to set a key to activate the console. Standard is the „^“ Key. After that, you can now use the Practice mode from the play menu and enable some of the console commands from this list right away by using the options on the left.

Note: For some of these commands you need to activate sv_cheats 1. This wont work on a official server, only offline, on a private localy hosted match or on your private community server.
