Tired of waiting to find that last person to fill out your party in Horde mode? Then we have good news. According to a post on the official Epic Forums, Gears of War 2 has received a title update that improves matchmaking speed. Specifically they addressed issues when there was a party of four and a single person.
This is excellent news as I know we've had plenty of users complaining about the constant waiting...waiting...waiting...found player...player left...waiting waiting...player found. Rinse, repeat, and curse.
Other issues addressed include some single player startup issues and a few bugs in regards to stats. Looks like it's time to fire up some Horde mode again!
