The next phase of Impulse will have built in voice comms, and I assume it'll be done in the Reactor so it'd work in Demigod without needing the client. But that part is just the assumption.
wahoo, that would be awesome! At first the absence of voice comms didn't bothered me, supcom was fine without, if you needed to be competitive, you could always use teamspeak, ventrilo,...
But you don't have a lot of time in demigod, even a lot less that the few seconds you were having to type important messages in supcom, so voice comms are really needed in the game. I play a lot with Sedna, and not being able to tell in the middle of a battle that i have no mana left for exemple is really problematic and frustrating. That feature should have been in the game since day 0.
