GameBusiness.jp traces proximity voice chat from those experiments through the 2002 Xbox Live launch, where the bundled MotoGP demo let riders talk to the three racers nearest them. Halo 2 formalized the mechanic in 2004 with Voice Proximity, where nearby enemies could hear a player\u0026#39;s conversation, paired with a team radio channel for distant allies. The feature also covers Splinter Cell Chaos Theory, where loud voices alerted enemy AI, and the Battlefield 2 mod Project Reality, which adopted positional audio through Mumble. The argument: a voice heard means someone is near, and co-op games like R.E.P.O., PEAK, and Big Walk build on that spatial information.\u003c/p\u003e","blueskyPost":"Proximity voice chat looks like a fresh trend in co-op games, but GameBusiness.jp traces it to the 2002 Xbox Live launch and Halo 2's Voice Proximity.
