its not rng based heres the strat to beat it for any new people playing.

spawn in get 900 buy kap 40 off wall

get 2500 buy quick revive and electric so if you get a free perk you dont get quick revive

run to the left building buy peacekeeper - farm points from peacekeeper door filling the steak

once you have 3250 go to the house on left get jug / shield piece

then hop across to stamina up house across from jug 2750 points try to have the exact amount so you can reset from staminup back to spawn without losing points

make your way to 3000 dollar wall finish filling up steak and get 5750 before buying 3000 dollar wall

then go over to the house on the right to get double tap then you can ether go to the house on the right that is 3000 or go get widows ether or works after buying 3000 dollar door there will be another shield piece and make your way upstairs to soul box fill souls and get the scar h as second weapon its in the painting then proceed to go over to speed cola door which is to the right of widows

then the last door is inbetween widows wine go get vultures aid youll need it to build the shield

last shield part is next to vultures aid go do parkour fill up soul box next to jug start hitting the box till you get wonderwaffle or thunder gun finish soul box

reset back to widows kill a zombie that has vultures aid gas sit in gas build shield then reset back to spawn start doing parkour to the end area

i suggest grabbing mule kick while otw to the end then train buy tommy gun as third weapon get the perk that gives weapon enhancements pap all weapons climb the parkour and you win

if you cant beat it get good
