Resident Evil 0 (N64 version)

Resident Evil Zero was originally to be made for the Nintendo 64 console. However, when the design was more than half-way finished, it was canceled. This was due to the planned release of Nintendo's newer console; the "Nintendo GameCube". The game was to be released at the end of 2000.

Little information was released, however the E3 2000 demo was recorded.

Similarities with finished version

 * The Ecliptic Express shares the same design and location of items in the E3 version as the finished GCN version.
 * Billy Coen was virtually unchanged when the game moved platform.

Differences with finished version

 * Rebecca Chambers is dressed more like Jill Valentine. In the game, Rebecca is seen with a beret and with heavy shoulder pads like Jill was in Resident Evil.
 * S.T.A.R.S. begins searching for Billy Coen to ask him what he was doing near a damaged prison van. In the GameCube version, S.T.A.R.S. begins searching for Billy as a secondary objective due to their belief that he had killed two MPs and escaped.
 * S.T.A.R.S. is not aware that Billy is a convict until Rebecca sees handcuffs on him as he runs away. In the GameCube version, S.T.A.R.S. find a report detailing him near the MP van.
 * Edward Dewey jumps in through the window, but his right hand and Handgun is missing. This was changed when the remake of the first game removed mention of a severed hand, with the body instead being Kevin Dooley.
 * There was at least one unused boss called D.A.L.I. which was much like a leech, though it may have just have been a scrapped leech mutation or even Marcus mutated.
