I understand the video title says only work on PS3 but it works on xbox too! Trying to get Importab to change it back to have it say xbox.
Thank you Importab for uploading the video!

An Xbox, Black Ops 2, Nuketown 2025, to be able to save a custom game.

Start by joining a party. (It can be your own.)
Then Go to Custom Games
Make a edited gametype (Do not edit amount of teams, Health and Damage settings, or Bots)(Sorry about no Bots but the game can't use bots online.)
Go to preset classes
Change it from global to Per-Team (Some Gametypes don't have this. If not then its fine.)
You have to have Amount of selections on 10 (Some Gametypes don't have this. If not then its fine)
Now change the map to Nuketown 2025
Next you have to go to change game settings
Then save that gametype.
Now go Public Match, Find Match, Whichever gametype you edited, then leave that lobby.
Go to Cod TV, then to friends feed, recently shared.
Then select the first video and hover over yes, (Do you want to go to theater)
Now you have to press A and B at the SAME time.
If done correctly then you should be in a online match.
Now you have to press Y (Shows Friends)
Press RB to go to Xbox Live Party.
Click on your GT, Then on Player channel.
Go to Custom Games.
Scroll over yes, Then press A and B at the SAME time.
It should put you into Custom Games
From Custom Games go to Change game mode
Click on Saved, Then on the edited gametype.
Now leave that lobby
Now go Public Match, Find Match, Whichever gametype you edited, then leave that lobby.
Go to Cod TV, then to friends feed, recently shared.
Then select the first video and hover over yes, (Do you want to go to theater)
Now you have to press A and B at the SAME time.
If done correctly then you should be in a online match.
Here's the tricky part, you have to invite enough players to start the match and you have to be host.
Once the games starts it should be a Edited Custom Game ONLINE.
Now Enjoy!

Q:Will their be a video tut?
A: We have one!

Q: Is it normal that I don't get Nuketown 2025 when I'm in the lobby?
A: Yes!

Q: If you mess up in one of the step what part should we restart from?[/quote]
A: Sometimes you can go back 1 step but other times you have to go after you make the custom game.


Q: When I go to my custom games after I press A+B from COD TV, it shows that I don't have any custom games?
A: Find a match then back out and it should be there. If not wait an 30 minutes to a hour.

Q: Do I need Nuketown 2025?
A: I believe so, No one without Nuketown 2025 has gotten it to work.

Q: When I press A and B it puts in into theater?
A: Double Check your pressing them at the same time then go down to my UDP Unicorn spoiler and read up there.

Q: When I save my custom game it says "ERROR"
A: Delete all of your custom games, Then dashboard and reload Black Ops 2

Q: I've been trying forever is there a way to force host?
A: Have the best connection. Even if that means make the other people turn on UDP unicorn.

Q: What Do You Mean By "10 Selections"?
A: When editing some gametypes under I believe custom classes it has "Selections" you need to make sure it is 10. 10 is the default amount of settings for online. Selections are the amount of items you can put on a custom class.

Q: Is this patched because when I press A and B at the SAME time it puts me in theater mode?
A: No it still works. It means you have too good of connection if that happens to you. Lag your connection and it'll work.

Download UDP Unicorn from this link: UDP Unicorn Download
Then open it and change the settings to the following:
Target: 27.27.27.27
Port: Call of Duty
Packet size: 15.0
Delay: 1 ms
Threads: 1
Sock per packet: 1
Ping Target: Idle
DNS: Idle

Now for steps:
Load UDP Unicorn and follow my guide from above.
When it says press A and B at the SAME time click attack on UDP Unicorn
Then press A and B then click stop unicorns.
Now you should have been pulled into a public match.

This will only work for some.
