There were errors in the script that prevented the perks "Victorious Tortoise" and "Widow's Wine" work correctly.
I fixed "Widow's Wine" with the help of a programming AI, but I didn't have any luck with "Victorious Tortoise"; one of the AIs I tried came close to working.
Since I wasn't making any progress, I had to improvise a sort of Frankenstein, half recycled code and half code invented along the way, until it worked correctly.

Fixed Script: https:/ /www.mediafire.com/file/qj1vnp9hshcjdc8/custom_perk_machines_EN_with_ai_6.6.gsc/file

Custom Perks Available

• PhD Flopper - immunity to fall damage and explosions and create an explosion that kills zombies upon diving to prone
• Widow's Wine - deals damage to zombies that attack you and slows them down (Now also works with grenades explosions) // Fixed
• Thunder Wall - launches nearby enemies into the air upon being attacked by 5 or more zombies
• Dying Wish - gives a second chance if you die
• Electric Cherry - generates an electric shockwave upon reload
• Ammo Regen - slowly regenerates ammunition of all weapons and grenades
• Executioner's Edge- gives melee attacks a one hit kill at any round
• Burn Heart - ignore lava damage
• Downer's Delight - longer bleed out time and use last weapon held in last stand

• Mule (on maps that don't have it) - additional primary weapon
• Bloodthirst - Gain health when killing zombies and can overheal for a max of 385 health // Small change
