With this mod you can do everything, you are an admin who can change and control the commands whenever you want allowing protection and fun.

If you don't have a dedicated server, on a local server it works by creating you in the lobby in any game mode. Remember that to use it in versus and scavenge mode you must deactivate the restrictions on the use of addons. In my description of my mod there is how to activate mods in versus and scavenge.

For more information about the mod commands, here is a guide by the author:

And here I leave my menu for quick use of each command so you don't have to write them in the chatbox or in the console.

And when you create your local server and put any command, the "ems / admin system" folder will automatically be created with various file options to configure.
