All vanilla gamemodes inherit this feature. But due to the configuration being locked, you can't enable it without rebuilding the gamemode from scratch.

This script fixes this issue! Simply add this mod to your server and enjoy your vanilla gamemode with a killfeed. Everyone can see every kill. Well ... almost every kill. Sadly the game currently can't detect the killer of explosive kills. So your juicy grenade kills won't show you as the killer.
