strong>Cush:
Would be too easy to abuse by people just typing it to get others killed, it also turns it into a habit to hit it, meaning pretty much everyone will always know last words instead of having to think about it and take a look themselves.
That's why I said the broadcast should be: "Z broadcasts Y's last words: <last words>"
It won't be a direct chat message, but something unique that you can't fake.
strong>Mr. Gash:
Just turn on always showing last words in chat.
That's something different. When last words aren't always showing, you will have to find the corpse first in order to broadcast.
Now you have to find the corpse, then waste time standing still to type in chat and explain; people might not believe you + you can fake it...
