The story begins with a desperate search for a missing partner in a city paralyzed by a sudden containment breach. As Detective Draven Vaughn, you must infiltrate the locked-down streets of Helga City after a mysterious bio-contaminant begins reanimating the dead. With the military sealing every exit, your first priority is reaching the police station, where Commissioner Frank Lawson is barricaded and holding on by a thread.

Survival in Helga City requires more than just a badge. You must scavenge for limited resources, manage your physical needs, and utilize a variety of weapons to stay alive. Customize your firearms with tactical attachments to gain the upper hand against an evolving threat. From abandoned high-rises to the depths of the underground sewers, every corner of the city holds a piece of the puzzle—and a new danger.

In Corpse Mansion, your choices carry weight. The decisions you make will ripple through the narrative, impacting the fate of the survivors you encounter. Will you reach the station in time to save Frank and find Avery, or will you succumb to the horrors of the apocalypse?
