Bungie's latest Halo 3 update is now live and you'll be prompted to download the, err, download, next time you fire the shooter up.
"You may experience a few laggier-than-usual games after the update is installed as it resets your hosting and network connection history. This history should grow rapidly for an improved situation," says Bungie.
Other minor tweaks include:
Melee contests have been rebalanced
Dying while performing a melee or weapon lunge will no longer accelerate the dead player
The Elite Commando shoulder armor variant has been unlocked for all players
Improved the "Prefer Good Connection" option
Added backend hopper support for DLC custom game variants
Fixed a problem with the Theater when a player tried to view a saved film for a DLC map he or she doesn't own
Fixed a UI error in the Theater when a party leader selects a film that is invalid for a party client
Fixed a bug that under rare conditions could allow a BXB sequence
Fixed a Dirty Disc Error that could occur when loading the same DLC map twice in a row
Added a visible version string to the Halo 3 main menu
