Thanks to Justin C for great mod. I hope it will do to make it better:
Dear players,
I bring to your attention a special patch for the Hardcore SK. So, in the original version as already knows, zombies are weak and don't represent particular danger for the player... Now, everything is changes! Zombies have ceased to bleed, not frostbitten limbs and don't feel pain .. their bodies become slightly susceptible to range weapons. Significantly increased survival and 15% faster. But they also have a weakpoint! Shoot in the head and you'd be right!
