You were a D-class in the SCP Foundation, a breakout has been made, an SCP has breached. you run through the halls, your orange labed shirt flowing as you run through the halls, the guards running around, D-classes are going insane, the alarms blaring, until you hear a voice. you look over.

You see a D-class, but its not normal. its got a mask on, the mask drips a weird black sticky substance from the eyes and mouth, it approaches you, curious and aggressive.
