Here’s my strategy for static mode, zombie count 150%, note that I take parkour expert, it is a lifesaver in cities.
I start off by looting the outskirts until I get a decent amount of storage, messenger bags and backpacks usually, I grab up all the food/drinks that will spoil first (pizza, frozen dinners, orange juice, apple juice, etc) and leave notes all over my map so I know where to go for tools/equipment/food later.
After that I collect up a bunch of rocks (60-80 depending on storage) and throw them at zombies, with very low skill and 10-12 dexterity you can usually kill a zombie with 4 to 8 rocks depending on your luck, I’ll lead a half dozen/dozen zombies out of town, stone them to death, then butcher and loot them.
Once I’ve got a decent throwing skill and/or a decent/good melee weapon, I head further into town, luring off small packs of zombies to a nearby house, pry open the window with a crowbar, climb inside, close the window, then smash it (A broken window takes more movement points than an open one). I throw rocks out the window until they’re severely weakened, then train my melee skill on them.
When my skills are good or I’ve managed to hit a gun store that had ammo and a gun that can use it (or hit 3 or 4 gun stores usually) I start to lure off larger and larger groups of zombies. Once I get a sub-machine gun or an assault rifle and a few hundred ammo I start running around town with a shopping cart and just looting everything, shooting off any zombies that get nearby, if I start to get swarmed I just switch to burst fire.
