Quick answer: Each zombie has skill progression, and official development material says red-skull corruption can improve a worker’s skill potential. That does not establish one best corpse or universal build.

What is confirmed

  • Zombie workers have individual progression.
  • Corruption is connected to worker potential rather than being only a penalty.
  • Zombies can work in production and fight in the undead army.
  • Choose a worker for the job you need now.
  • Track how the relevant skill changes actual output.
  • Reserve rare upgrades until the effect is reproduced in the current build.

What not to assume

Avoid first-game white-skull and 26-skull guides in sequel searches. Those results are heavily polluted and are not a valid sequel tier list.
