Rumplehedskin started a now-stickied thread on the Epic forums describing a new server he set up in which he is heavily modifying how the Warfare gametype plays.
Catch the forum thread HERE and watch the video below which showcases one of his concepts. WAR Deathmatch! In this gametype, killing other players damages the core! He has several game mods like this and they can only be played by joining Rumples Bloodshed server.
