How to Use The Admin Commands
Logging in as Admin
Press Tab, or whatever you have bound your console key to, and type;
example = enablecheats pass123
From here, you can enter commands.
Whitelisting an Admin
This allows you to use commands without needing to log in as Admin.
Create a file in the directory \ShooterGame\Saved\ called AllowedCheaterSteamIDs.txt
It should look like this \ShooterGame\Saved\AllowedCheaterSteamIDs.txt
From here, list on each line the Steam64 IDs you wish to authorize for cheat commands; these users will be able to cheat without logging in as Admin.
