Developer-published fixes
The Steam Community Hub’s “Demo Fix Update” says the game added microphone selection, fixed issues with proximity chat, and fixed issues with the walkie-talkie. Treat that as the build’s published change history, not a promise that every later build has identical controls.
Safe troubleshooting order
- Choose the intended microphone in the game’s audio/voice settings if the current build exposes the selector.
- Check Windows input permissions and make sure the correct microphone is the default communication device.
- Test with one teammate in a quiet area before relying on voice near an enemy.
- If proximity chat is delayed or silent, note the build, input device, player count, and whether the walkie-talkie behaves differently before reporting it on Steam Discussions.
Why silence can be a mechanic
The official game page says the proximity chat system lets enemies hear players. A quiet microphone can therefore be a deliberate survival choice, while a broken microphone is a technical problem. Test both cases before concluding that voice chat is disabled.
