In this expansion the team has an extra mission to accomplish in order to win the game. After defeating the Nemesis, they must safely reach a helicopter that's circling above in order to escape the doomed house of Doctor Mortimer. As soon as the team has defeated the Nemesis, the Darkness track is reset and the team is given 4 turns to reach the helicopter. For the team to win, at least half of the survivors must escape the house.
