Having issues with Gears of War 2? Golden weapon codes not working? Laggy, slow matchmaking? An itching and burning sensation? Well your in luck because Gears 2 community manager SixOkay has the answers to all your questions over on the official Gears 2 forums.
I know for me personally I've had some issues with matchmaking, so it's good to know that Epic is aware of the issue and looking into a solution. Also, if you've played the game in co-op, some of the gamerpics aren't working that you are supposed to unlock - the fix is coming alongside the NXE on November 19th.
