Voice Chat
Overview
Voice chat is an essential part of Intruder's gameplay. It is transmitted in 3D, so you hear the voices of the other players based on their positions. Everyone can hear you talking - teammates and enemies alike - so it is important to always be aware of who could be listening. Voice volume also decreases with the distance; if you want to talk to someone far away, you can use the Radio. Voice chat was officially announced in the seventh update video.
In Build 1169, microphone volume boosting and volume sliders for individual players were added.
Controls
You have to press and hold a key (by default "c") to be able to speak ingame. This is very useful if you don't want to accidentally reveal your position (e.g. if you are in a noisy environment). On previous versions of the game you could set your mic to "auto" with a volume threshold, this was later removed due to people letting it on as it clogged network traffic[1].
