If it would be possible you should make a battle royale server where after a certain amount of time you would have to go to the NW airfield and fight. You could team up with anyone that you find on the map and make an alliance. You would also have to make it official so that your specific allliance could win. Or do something like a "who's going to eat the berries?". I think that a lot of people would join this and play it. I also think that it may just become a bloodbath like normal days bit it is worth a try.
