Dying Light 2 Stay Human - NC Tower Secret

The game takes place after the events of Dying Light; the 2015 rabies-like outbreak in the fictional city of Harran (the setting of Dying Light) ended with the “death” of all of the people in Harran. The international organization called the Global Relief Effort (GRE) was eventually able to develop a vaccine for the Harran Virus, ending the threat of a global pandemic, but the GRE continued experimenting on the virus in secret, intending to use it as a biological weapon.

In 2021, a mutated variant of the virus, named the Tachytransmissive Harran Virus (THV), escaped a GRE lab and started a second, more deadly pandemic that spread faster than the first, sweeping across the world and causing millions to transform into monsters. In an event called "The Fall", the GRE’s vaccine and "Antizin" (antidote that delays the symptoms) became ineffective against the new strain of THV, but if an individual were to be infected their symptoms could be suppressed with ultraviolet light, which could also be used to ward off and harm the infected.

By 2036, fifteen years after the Fall, much of the world's population has been wiped out, human civilization has been reduced to a handful of scattered settlements, with the fictional walled European city of Villedor being one of the largest. Originally quarantined by the GRE, Villedor was spared the worst of the pandemic thanks to its quarantine walls keeping the hordes of infected out of the city. Control of the city is split between several factions, including the militaristic Peacekeepers, the independent Survivors, and the violent Renegades.

The main protagonist Aiden Caldwell is a Pilgrim: an individual brave enough to make the dangerous trek between human settlements. He decides to travel to Villedor in order to search for his lost sister, Mia.
