Clocking in at 142 megabytes, 1.02 looks to be intended on improving on the live updates that Naughty Dog has placed on the servers in the background, and the official statement on the Naughty Dog website reflects that:
"As many of you may know, especially if you are among the many, many, many people who have been playing our Factions multiplayer mode, that some people have been experiencing long wait times while trying to find a match. We’ve deployed several LiveUpdates over the past week in an effort to improve the matchmaking wait times. Things have definitely improved but there still remains work for us to get the matchmaking experience where we feel it should be. Patch 1.02 is our latest effort to continuing improving the matchmaking experience."
Following the statement, PR arne, as listed on both Twitter and the Naughty Dog website, continues by saying that the team will be monitoring the servers in order to keep addressing the outstanding network issues.
Be sure to let us at PSU know if the update has made a substantial difference in the extended wait times for matchmaking.
