when you press TAB and open the map, you will now see how many players are currently in each faction (given that there are other players). There are also nav markers on the map for each player in the same faction as you. When you load in, you're in the "Villager" faction. But then you can either join blue (House Denivir) or red (House Piricious).
Next I was going to try to add some text chat, and then maybe some proxi mic chat.
