Soul-Eating Elixir

This secret medicine will cause a huge change in the body after being injected. The defense against bullets and physical attacks will be greatly increased, but only claws and fangs can be used to attack. Bite the enemy to suck blood and infect the target. After death, people who inject this medicine and those infected with the poison will turn into undead zombies and attack humans and continue to spread the poison. * The medicine is not stable after being injected into a living body. Any change in the body's state may render the medicine ineffective. * Can only be used in Arena mode.
