This mod creates new force for each player. Those forces are enemies (you can use diplomacy mod), but they can share vision despite being enemies (check out settings->mod settings->per player) now finally radars don't always share vision. Every player has option to flip setting, so that his radars share/don't share vision. If you want also to have shared chat between all forces, I might recommend you always-shout mod ( https://mods.factorio.com/mod/always-shout )
Game API allows for creation of up to 64 forces. Keep that in mind when composing with other mods, or adding on server that will have many players.
