DEVS considered push-to-talk feature
In your input.ini file you will find the following line:
ActionMappings=(ActionName="PushToTalk",bShift=False,bCtrl=False,bAlt=False,bCmd=False,Key=Q)
So the devs had at least cosidered/tested voice coms for solo survivors. The question is: Is it something planned to happen or just a relict from the past and already thrown away

What the game needs is killer push to talk
