I have beaten the campaign twice without cheating

Does anyone know if there is a way around this? I know you can edit the .pak files and change cvars in there but I have absolutely no idea how to open them lol. Plus i have a feeling i could really mess something up by doing that. Either way there has to be a way. Maybe the next patch will re-enable them for single player if we r lucky.....along with a map editor.....
still its an awesome game tho
