Epic has posted the Title Update 6 patch notes for Gears of War 2 and the biggest bullet point has to be the ability to join matches in progress. Not only can players now join Horde matches mid-game, the update adds a new Social Xbox Live playlist which lets players join matches in progress and doesn't penalize those who quit early -- but it's only available to those who have all of the DLC. The new Social list also bypasses matchmaking screens and cycles to the next map immediately following the conclusion of the current match, cutting down on the time spent in menus.
The update addresses certain exploits, such as the ability to get out of the map on Subway and Blood Drive, and also improves the pellet grouping on the Gnasher shotgun "to increase hit consistency." Rod Fergusson, senior producer on Gears, says players can look forward to downloading the update in "about a week." We'll let you know when it's live.
