```
dotnet %~dp0DepotDownloader.dll %* -app 730 -depot 731 -manifest 7043469183016184477 -username STEAMUSERNAME -password PASSWORD
dotnet %~dp0DepotDownloader.dll %* -app 730 -depot 732 -manifest 4047004309608881181 -username STEAMUSERNAME -password PASSWORD

9. Steam needs to be open with a CS:GO account, then just double click csgo.exe and it should launch in insecure mode. Don't use your main account to prevent bans.
