Save your game at the helipad. Go to the Magic Door. Walk through it ten times. Do not fire any weapons. Survive for five minutes.

Instead of loading into a new room (like an office or a stairwell), the game loads you back into the exact same corridor , facing the opposite direction . You have walked through a door only to return to where you started. It is a doorway that leads to itself—a topological impossibility.

Your character—either Elza Walker or Leon Kennedy—performs the standard "door opening" animation. The screen fades to black for loading. These transitions were a hallmark of classic Resident Evil , hiding load times behind a cinematic pan.

But then: the magic happens.
