It has been 2 centuries since the Final War ended, mankind dying off to extinction due to Earth being inhabitable by air quality and other factors. Life on the planet was dead, no sight of life to be seen. However, through a portal was Hell, a sentient place humans found out of curiosity before being extinct. There lived a lot of species and machines like Drones, Husks and many more. Machines relying on blood to live have started to kill each other to feed off each other’s blood...

For a lab, humans used to experiment on the species in Hell, taking them through the portal. They would do experiments to see their limits and possibilities, making them stay in cells for isolation. When the Final War hit though, the human population was erased, leaving the experiments to roam the abandoned place. They had themselves and other entities to interact with…

Files and experiment notes were scattered everywhere. There was even a mysterious red liquid on some notes, probably blood. There were many hallways that led to many cells/rooms. There were some soft noises around the place as you explored. Seems like you may not be alone…
