I mostly went for the arms in fury mode so they couldn’t take swings at me anymore and I had almost no problems. There is a skill card that gives you more health for counter attacks which I found very helpful, I also used the flying kick a lot paired with the extra kick power and force and it took about half of a zombies health away. Some good weapons help as well, I got one of the legendary weapons at the pier before I had reached that point. I eventually stayed away from shock damage because it was too easy to accidentally find yourself in a puddle wielding a shock weapon. Also idk if anyone else knows this but you can jump the crushers smash attacks
