Great news - Patch 1.6 (with Map Pack 3) is finished & now in test over at Activision!

Barring any problems popping up, it should be released in accordance with the PC Patching.

Below is a list of what is included in the patch:

3 new Multiplayer maps: Battery (mp_drum), Breach (mp_bgate), Revolution (mp_vodka)!
New Nazi Zombie map: Der Riese (nazi_zombie_factory), an all-new Zombie map set in a secret Nazi research facility featuring the Pack, A Punch Machine, Teleporters, and many more undead hordes!
Exploits pertaining to Demo playback.
Favorites list now ignores filter settings.
Fixed S&D round counting error when roundlimit is reached.
New feature: in-game Add to Favorites.
Friends list: green online indicator.
Starting the game in Safe Mode will no longer toggle the “Soften Smoke Edges” graphic option.
Fixed various crashes.
Mods: Client will no longer join a modded Co-op server via Game Invite unless they have that mod loaded.
Mods: Client running a mod will be asked to unload the mod if they attempt to join an unmodded server.
Mods: All singleplayer levels can now be run with a mod loaded.

Additionally, we do expect a concurrent release of the Mod Tools 1.4 package, Linux dedicated 1.6 bins, and the Steam 1.6 day-of-date with this patch. More details on those will be made available once they get cleared through testing.

So touch up on those Zombies skills; Der Riese is on its way!
