The "A-Hole Button" as they're calling it brings up a score list with everyone's tag on it. By using the right stick, you can quickly select whichever player is smack-talking you into a stupor, and you won't hear from them again.
"Any muted player you have selected in your Xbox Live account overrides Halo 3's new system, but that should actually enhance the choice of maroons you're editing out of your gameplay. Best of all, it means fewer wasted or frustrating gameplay sessions," Bungie's Frank O'Connor notes.
"We're doing our best to come up with lots of smart solutions for stuff like this, but honestly, we can't be parents to some of these poltroons. We're much more concerned with giving you guys the tools you need to silence them."
