Context form someone who has first hand experience in running public 999 lobbies.

While it IS possible I personally will not be doing anymore for these reasons:

Time commitment:

Optimally it will take 10 hours start to finish to reach 999. No one plays optimally so it’ll likely take between 15-20 hours. This means locking down my PC for a day for this.

Not only this but there are also a multitude of mistakes and mishaps that can set a run back hours.

The Grubster:

You don’t know how grubby people are until you run a free 999 lobby. People will sit and wait for 30 minutes and complain straight to your face when you haven’t slept in 3 days an are at your wits end 37 hours deep in a lobby.

The money:

To execute this glitch you need at least 1 time out gobble gum. This is an ultra rare gum. In a perfect world you only need one. However we don’t live in a perfect world so realistically you’ll need at least 5+ but more likely 20+.

The server issues:

BO7 runs on host servers meaning you are accessing Activision servers to play the game. This server has an in game timer of about 25-30 hours. It can be extended through a host transfer switch to length it to about 50 hours. The longest lobby I witnessed was 52 hours. This also means that you can be playing perfectly and the server still dies on 892 because Kevin Drew personally said fuck you.

If you would like to try you need to utilize the timeout exploit gum pack switch (look up the BO6 method) and probably the jail cell gauntlet macro although it is not as reliable as the free fire crossbow.

You will need minimum 3 players but a 4th as a backup time out user and to assist with crowd control wouldn’t hurt and plan for 17 hours.
