Can you please make it possible IN SOLO to hear each others mic, with volume adjusting to distance parralell with the fotsteps, so that we can shout friendly and chose to trust someone to team up for as long as the trust lasts :-D In real life someone would team up and then backstab the other one some where along the way. and with possibilities to revive/heal during battles. This makes the game more real with trust and honesty dilemmas along the way.. Or some sort of quick-dubbeltap to wave or flashing with a flashlight, green/red flares or some way of signaling a sort of temporary parle with another player :-D
