Terminus

Civilization deconstructed itself like a riot in a madhouse. One minute it all functioned with a standard sort of craziness, and the next it devolved into ten billion psychotic inmates at each other's throats like suddenly sprung animals. Survivors refer to civilization's final irrational act as 'Terminus', but this is an unofficial label. It simply gives them a handle with which to wield the concept of their end times. It bifurcates their memory. Before. After. In between, an unspeakable river of blood.

In the aftermath, a handful of guilt-wracked holdouts stumble onto a terrible secret. They discover the cause of the catastrophe, but the answers they find only beg further questions. Resolving this last great mystery soon becomes a matter of life and death, and the fate of humanity hangs in the balance. To learn the final truth and save their species, they must cross a blood-soaked wasteland where they confront and overcome hordes of crazed lunatics and ravenous chimeras to investigate the long-standing enigma we call "Area-51". Post-apocalyptic revenge is sweet!
