Suggestion- Battle Royal modes

I have been playing the Battle Royal game modes with friends lately and I was thinking about how to make it more interesting/engaging. Please for the love of all gamers, add a duo Battle Royal and quad Battle royal game mod with adding Zombies to the map randomly in buildings and also groups of 8-10 zombies wondering across the map. The aggressiveness can also be random. That brings an added environmental hazard. So not only are you fighting your way to victory, but you also have to now survive even more and kill everything in your path. I can not think of another Battle Royal game that has added Zombies to the mix. This could possibly be a first.
