9 years ago	Let's add some mystery into the mix! Hello everybody, Time for a new update on the development. I have been working hard on Subject A-119, a couple of rooms have been added of which I want to share one specifically. It is a cell, but what could it be used for? Novacore is a research facility after all, why would they need an isolation cell? Find out on 07/07/2017!	—
