We are on broadcasted warfare right? It's like a whole spectacle with advertisers and everything? How cool would it be if when a squad got wiped an announcer comes over an intercom that everyone can hear "Oodaboogah's squad has just been eliminated" etc. Making things more fun and dramatic like it's some big spectacle. Maybe even Halo style narrations when you're on kill streaks. "Double Kill" "Triple Kill" etc. Little things like that add to the adrenaline.
The announcers voice should come out of a loud speaker though kind of like the combat DJ, like it's announcing it to the world. "Only 3 teams remain." Things like that would be rad imo.
