The Devil would like to see you. Yes, you have an appointment already. Someone's already dispatched to show you the door. The Lucifer Within Us trailer shows someone's murder and the subsequent gameplay where you investigate it using statements of potential suspects to logically discern what is truth, and what's a lie. Find out who's the murderer and banish the daemons that hide and coerced the perpetrators for committing these vile acts.
We're well past dancing with the Devil here
