The Apartments

The Apartments is the first chapter of the No Mercy campaign. In it, the Survivors start out on an apartment complex's rooftop, which can be seen in the game's trailer. They must initially work their way down, through apartments using stairs and holes in floors. Once at the bottom, they exit to an alleyway, then to a main street. Several cars can be found along the way; a police car will sometimes have a second pistol, other cars may attract the Horde if they are shot at, as their alarms can go off.

The Survivors will eventually find their way to the Subway.
