A few radical ideas: I'd like to see a build of the game with only pistols and shotguns, and very low ammo spawns. Maybe very, very few scoped hunting rifle spawns, but with such low ammo that you'd be lucky to be carrying more than 2-3 shots. No high end, shiny-loot, long-range, high-rof military weapons. Not even any cqb assualt rifles/submachine guns. Make pvp happen up-close-and-personal. And within the context of likely drawing the horde. If you make pvp have to happen when the initiating party is likely to draw aggro first, then you put a natural brake on KOSing. Increase zombie spawns, and put zombie spawns in all the treelines around cities to keep campers/snipers on their toes even that far out. More melee weapons, to help new players deal with the increased spawns. Maybe new players spawn with a basic, close range club. It's not zombie survival without a frying pan! Super low spawns of food and drink/clean water. Make basic survival from starvation/dehydration your main concern. And you've got so few rounds, you have to weigh whether you want to open up a firefight, or save them for zed defense. Then the last twist: make it so deaths from gunfire can potentially damage the loot of the killed player... 50% roll on every item being destroyed from each shot. Scenario: Player A has a nice weapon/gear. Player B ganks him for it. Player B's shots hit that weapon/gear and destroys some/all of it. Player B is now out scarce rounds for his own weapon, has murdered a potential ally, and likely has drawn the attention of the horde. Will he even have time to loot his murder victim before the zeds are on him? Player B could of attempted diplomacy and traded for what he needed. He made the selfish, easy choice and suffered worse for it. Or he could of gotten lucky and made out like a... well... bandit! And he had to do it all up close, inherently putting himself at risk. Make everyones' choices have consequences. And the more self-serving choice has the much higher chance for both risk/reward. Right now, the most self-serving choice (KOSing) maximizes rewards while minimizing risk.
