I had no idea what the update did, or why, but according to friends, it did this:
- Mercenary Mosh Pit (Because S&D didn't need it)
- New RDS reticles
- Zombies Leaderboard patch (Stop a previous game overwriting info)
- Quickscope patch (Heard rumours)
- Split Screen spectator patch.
If you know any others or wish to confirm these, please do so. I don't have much reliable info at this point.
Copypaste from a blogging site:
• Matchmaking improvements to return higher quality results faster. This change includes settings that are tunable in the live environment, so tweaking may continue beyond initial release of this update.
• The in-game store now hides DLC map packs that do not match the language of the player’s disc to decrease the possibility of users downloading the incorrect language version.
• Calling in a Chopper Gunner immediately after getting shot down in a Gunship will no longer end the Chopper Gunner run prematurely. Required timing-specific button presses.
• Split screen players are now able to change camera perspectives and cycle through players as a spectator.
• Addressed an issue where the most recent match played in Zombies could overwrite the best match played on the leaderboard.
• Improved Zombies lobbies to prevent players from erroneously receiving the error “Unable to join game session” under certain circumstances.
• Addressed a number of community-discovered Zombies gameplay exploits.
• Additional security feature updates.
Gameplay Tuning:
• Additional sniper rifle tuning.
