Please note that mumble works with all games as a regular voice chat application. The games below are the ones we've added positional sound support for, so that the voice of your teammates come from their direction in game. To enable specific game support, make sure that Config|Settings|Plugins|Transmit is set to "Position", and that Config|Settings|DirectSound|Method is set to "Panning" (or better).
* Battlefield 2 (1.0.2) * World of Wardcraft (1.8.4 EU)
If you are an active Mumble user and would like to see support for additional games, submit it as a feature request on sourceforge.
