Markland Hospital

Markland Hospital is the first and final setting of the Half-Life mod Afraid of Monsters and its major update Afraid of Monsters: Director Cut.

History
The hospital is first revealed to be a several-story high medical institute under construction and bathed in daylight, but when the game's protagonist David Leatherhoff travels to the hospital in search of help against his drug addiction, he overdoses on an enigmatic pill bottle in the bathroom and imagines the hospital to be a zombie infested hell drenched in darkness.

The events follow David, after waking up from a drug-driven nightmare, in the bathroom, and after exiting, realizes that it is suddenly night, most lights are switched off, and there's not a human to be seen. His one escape is blocked by a family of fluroescent light fixtures, which spilled out of their stables and blocked the hallway with its dangerously electrified wires.

As such, David travels to the generator room to deactivate them, which turns off every single light in the facility, and hostile zombie-esque creatures called Twitchers spill out of the shadows to attack the addict. He eventually escapes while armed with a pistol and kitchen knife and ventures into the city.
