San Antonio Haunted Houses

 Something is spreading through the city.

Cracked streets, flooded tunnels, and crumbling buildings stretch for miles, each one infected by a mysterious chemical plague. Those exposed to it have become twitching, unstable shells of their former selves, wandering the ruins in search of their next victim.

At the center of it all is The Pharmacist, a deranged chemist who uses the city as his personal laboratory. His experimental concoctions seep through every alley, subway, and sewer, transforming the district into a nightmare of decay and mutation.

The city is his laboratory now and every visitor is his next test subject.
