This serum contains the necessary antibodies to fight the infection that Eveline spreads. You receive two vials from Zoe, which are used in the following places:

  • The first must be used to permanently defeat Jack when he attacks the Boat House.
  • The second can be used on either Mia or Zoe, the choice of which decides which ending you receive when you complete the game.
