The next major issue with proximity chat is that you can turn it off. The game's settings do not make it clear what that means exactly, but it probably means that those disabling the feature will not be able to hear other players outside their party, nor be heard by anyone else. If players are somehow able to talk without their comms registering on proximity chat while still hearing other players, that would be a huge advantage for players disabling the feature. There's also the possibility that some PC and Xbox players are using a third-party client such as Discord for their voice chat, which could allow them to eavesdrop without being heard themselves. Much like the third-person mode, which I haven't sampled yet, this might be a feature that warrants its own playlist rather than serving as a toggle bar in the game settings menu.

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).
