Due to the Map Pack 2 release for Call of Duty: World at War. Developers at Treyarch released a new patch right along with it...
*Here are some of the Features
-Significantly streamlined MP matchmaking.
- Increased the number of safety checks in the MP spawn system to prevent players from spawning within the line of sight of an enemy.
- Implemented a new stats backup system – this system creates a regular backup snapshot of player stats; if the game detects data corruption, instead of attempting to reset the player to level 1, it will notify the player that their stats have been restored to the most recent backup.
