This will revert you back to the default settings and you will be able to connect to online servers normally again. You can simple disable the mods by going into your Mods at the Main Menu and hitting the disable button.
When you enable any mod on Black Ops 3, you are isolated from the official dedicated servers so you cannot interfere with others. Will this prevent me from connecting to official multiplayer servers in the future if I use this? Any progress made using mods will not be carried over. Just follow the 'How to.' guide above, no other tools are needed. Do I need any other tools to get this to work? You can join other player's games also through the Server Browser in game. Yeah, you can still play with others online through private matches. Can I play with others online though still or is it only solo?
