The prototype of RE 4, much in the same vein as RE 1.5, this was almost complete and not surprisingly was completely scrapped. I'm sure alot of people know about these, but the one that caught my eye the most was the second version, which is really strange(And scary as hell), I have no doubt in my mind that had this been the final version, as opposed to the one we know, it would have been way scarier. However, the plot was so far removed from the traditional Resident Evil that it was scrapped as well. Basically Leon was infected with the Progenitor Virus, but here's where it got weird. The enemies were things like moving suits of armor(which served as the basis for the resilient Armaduras) and living dolls wielding things like kitchen knives, whenever these enemies awakened, the screen would tint blue, and would gain a slight grainy quality, almost as if Leon was hallucinating. However this was something closer to what one would expect out of the Silent Hill series, and it was deemed too paranormal by Capcom. I find it disappointing, sure it deviated from the norm, but hell, it looked interesting.
