Mercy Hospital

Mercy Hospital is a large, thirty floor hospital located in the city of Fairfield. Getting to it is the central objective of the campaign No Mercy. In the beginning of the campaign, a helicopter pilot instructs everyone who is not infected to head to the helipad on the roof of Mercy Hospital for evacuation. Chapter 4 and Chapter 5 of the campaign reveal that all of Mercy's patients and staff have been infected, and the Survivors must fight through the hospital to get to the roof, and then defend their position on the roof until rescue has arrived.

The Hospital appears to be one of the first places to have handled The Infected. This can be said by looking at the containment efforts (isolation rooms) near the elevator, which are the rooms with biohazard signs outside them. On these signs, Mercy staff have marked the virus as "N/A", meaning they had no idea what the virus was and did what they could to separate the infected from the public. The 28th floor was still under construction before the outbreak, and was abandoned after it began. This is observed by the Survivors when they ascend the elevator, and travel through the maze of wooden frames to find a safe room. By looking at the skyline of Fairfield while on the roof, Mercy Hospital appears to be the tallest building in the city.
