You make a living by attending to an asylum house; delivering patient medications, checking to make sure that they took it, guiding them with the day's activities and checking up on them and assessing their rehabilitation. One day there was a slight alteration to the pills that the psychiatrist gave you. You got curious but trusting his methods, you brushed your doubt aside.
On your break time you checked the medications room to look for that exact same pill. You found out about the effect of the pill, turns out it triggers a human beings killer instinct--tapping into the primitive side of the human psyche. You hurried to the asylum's common room and to your horror the patients were in fits of rage. An asylum bloodbath. Try to escape the situation before it's too late.
