The Hotel

The Survivors start on top of a hotel converted into a evacuation center, recently swarmed by the infected. The Survivors witness the helicopters moving to a different location, and decide to follow them through the city. The Survivors become acquainted in an elevator and the Survivors must pry the elevator doors, making a loud screeching noise that summons the horde. Afterwards, they must fight through the remainder of the hotel, which is on fire.

Trivia

 * This hotel is featured in the Zombie Survival Guide trailer, when the Survivors are seeking to get to the evacuation center.
