I think it would be better if you had it play another sound to the other team.
what i mean is if there are 10 per team, and 9 CT are killed and only 5 T are killed, the last CT hears "you are the last man remaining" but the 5 T remaining hear something diff.
something like "one man left"
other ppl might have better ideals of something to play.
that would be really cool if you could do that.
