Collect the killerducks that spawn in the maps to become the killerduck. Earn points for all 3 seconds of carrying the killerducks. As long as you carry the killerducks, you can receive damage, every other player is invulnerable. You can drop the killerducks or you can lose when when you die. If you die, they are respawned randomly on a player spawn points. This ensures that they are reachable.
The killerduck-player is visible because every 3 seconds a score point event with an icon is spawned that is visible through the whole map.
Note
A few things might be obsolete here, as I didn't know about the linked ticket that already describes a similar game mode. A few things differ in my quick implementation.
