Gears of War 3 is getting its Title Update 2 this evening at 2am PDT. Here's the list of what's changing; the biggest update is that the game is getting a spectator mode for gaming leagues to use which will turn the normally 5v5 matches into 4v4, with each team getting an optional spectator spot. Players grinding for rewards will appreciate the update as well, as the Leader and Vengeful medals are easier to earn, as are the Roadie Comet and Regen Enemies mutators.
The update also tweaks some UI functionality, including adding an indicator during King of the Hill matches, and adding the option to remove the UI for machinima and video producers. And there are a few bugfixes as well -- host migration in Horde will now stick to the same wave as when it happened, and there are fixes for the lost progress and profile freezing issues that players have experienced.
Fergusson says the update will bring down the game's dedicated servers temporarily, and players will need to restart their games to load it up. But follow those instructions, and you can be back to scratching all of the grubs you want.
