We just pushed updates to many of the multiplayer maps in UNCHARTED 2. The updates include steps to prevent the use of exploits, such as glitching out of a map, which prevent unfair situations in matchmaking.
The next time you connect to multiplayer, the updates will be synced during the connection process—this is not a Title Update to UNCHARTED 2.
We’re working on another similar update for more maps that we hope to launch in the near future.
