Above are the Counter Strike 1.1 and Half Life 1 commands, there will be codes that are only used for CS 1.1 and each code number is only effective when used for each game. If in Half Life you can use the commands arbitrarily when playing Single mode, if playing with friends in Half Life or CS, please apply the command parameters rather than the commands that are beneficial to you.
Maybe in the near future, the console command window will appear in Counter Strike 2 and you can also use some of the above commands to help display the stats. Counter Strike 2 is still in beta so the number of players will be limited.
