The game ends immediately when:

Human Victory:

The Human Players have completed all 3 Objectives.

Zombie Victory:

There are no more Survivor Tokens in the Courtyard and then either a Human is “Eaten Alive” (see Eaten Alive) or the Barricade Token reaches “0.”

After all cards in the Search Deck have been revealed, each Human Player has taken one more final Turn, and the Human Players have not completed their Objectives.
