The announcer

The Announcer is the Male voice in the Halo: Combat Evolved, Halo 2, and Halo 3 Multiplayer that shouts out certain phrases when the criteria are met (like the Announcer shouting out Medal names when certain Medals are obtained and general Events in the game).

The Announcer is voiced by Jeff Steitzer
