What it was
The abandoned first major production version of Capcom's Resident Evil 2.
The prototype paired Leon Kennedy with motorcycle racer Elza Walker in a more modern police station and used different enemies, supporting characters and progression.

Leon and Elza explore a substantially different Raccoon Police Department.
Footage and screenshots show the prototype through magazines and trade events.
Capcom cancels the advanced build and restarts Resident Evil 2.
The redesigned sequel reaches general availability.
An incomplete preserved version becomes available outside Capcom.
Why it ended
Capcom judged the late build insufficiently coherent and restarted production, replacing Elza with Claire Redfield and redesigning most environments.
Last confirmed trace
Magazine footage, promotional discs and an incomplete leaked build preserve the prototype, while fan teams have attempted reconstruction.
What it left behind
It provides a rare playable comparison between a commercially important game and the advanced version its studio chose to discard.
