In the vast, often shadowy world of video game preservation, few discoveries generate as much excitement as a lost prototype from a major franchise. For years, the tale of Resident Evil 0 on the Nintendo 64 was the stuff of urban legend—a game that was announced, showcased, and then seemingly vanished into thin air.

Pressing the Z-trigger instantly cuts the camera to the other character, even if they are on opposite sides of the Ecliptic Express train.
