The Good
You ok there? - Zombie's falling from heights into a crumpled mess is A+.
Candy - Best addition to the game and lots of variety to aid your playstyle.
Head tracking - Spooky and weird but also helps with headshots so win-win.
Gamestage loot - Tiered correctly, I shouldn't be...
Modded Steel knuckles with Bar Brawler, Brawler 5 and S. TRex absolutely wrecks mid game zombies. The problem is once you start getting arnored or irradiated zombies.
I can see what they are trying to do, they don't want vehicles to be a safe haven in a survivalist game.
I would rather they make vehicles more costly instead, either make gas rarer or drain faster.
