How do I create my modded lobby on gears of war 3
Create a private match and invite friends. Feel free to tweak settings. Or, you can host a modded lobby.
There is no such think as modded gun but there is a modded controller.

No, You cant even Play on xbox live with a modded xbox 360 or modded game
