'Warzone 2.0′s' Gulag, proximity chat, new modes and more

This time around, some of the things you unlock for one gun can carry over to another. These are universal attachments such as optics, muzzles, ammunition types and underbarrel attachments. For example, if you unlocked a suppressor or 4x scope on an M4, it'll be unlocked and ready to use on another gun that's compatible, such as an AK-47. Then there are attachments such as barrels, lasers, stocks and receivers that are platform-specific. A platform is a subcategory for variants of a gun modeled after a base design: The AK-47 platform includes the default AK-47 (assault rifle), RPK (light machine gun) and AK-74u (submachine gun).
