Mercy Hospital

Mercy Hospital is where the Survivors are instructed to go to at the beginning of No Mercy. It is a hospital in the city of Fairfield. In the beginning of the campaign, the Survivors hear that a helicopter pilot is looking for Survivors, and that they should head to the roof of Mercy Hospital to get out of the city. Chapter 4 and Chapter 5 of the campaign reveal that all of Mercy's patients have been infected, and that the Survivors must fight through the hospital to get to the roof, and then defend their position on the roof until rescue has arrived.

Mercy Hospital is a large, thirty-floor hospital that has an elevator that leads from the 4th floor to the 28th floor, an isolation room (the possible location of the first victim of the infection), and a fully functional helipad on the roof. 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.

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, previous 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.
