Zombies

[Jadefalcon]

Hi everyone!
I hope someone can help me cause I'm stuck. My Chars are now Lvl 41, my team is complete (Boar, Kruger, Sullen, Demon) and I think I'm reasonably equipped. Now I have to investigate the "rich" zones Demon pointed out. Tobacco plantation and old mine are finished but I can't beat the cemetary. Because I can't kill the Zombies. After a while they always rise again. Is there a way to kill them permanently?
