Its been a long day at Site-19; testing, getting tested on, fearing for your life because of the large Containment Breach that has occurred. You only have one goal, making it through this hellhole of a facility and reaching the Surface Zone. There are many SCPs that have been set free, each of them being a serious threat to your continued wellbeing. You take the place of either a Class-D, or a Researcher. Work together with one another, or don't. It's every man for himself down here.
