Plugin? If so, open source?

Is there a specific name for the plugin used on all of the survival games servers that makes it feel all Hunger-Gamesy?

Like, how when you kill a player you hear thunder and it says a tribute has fallen.

And if so, is it an open source? If not, I understand.

It is a closed source private plugin
