New patch items *UNCONFIRMED*

I understand that the thread could be closed because there already is a thread with 18 pages of speculation, but this is just from what I've seen, puzzles and all.

New Weapons at least seem to be.

New SMG: M12S

New BP Weapon: M4A1 Silver

New GP Weapon? It's the gun the GSG is holding in one of the puzzle pics. Looks like MSG-90 but you can't be so sure.

New MM Map: Lost City

New GM Map: Laboratory 2

General additions to the game as well.

Hmm, seems overall like a nice patch.
