Resident Evil 3.5

The fan name for the Resident Evil 4 Beta test.

Like most beta versions of the main series, significant changes occured between Beta and release.

3.5 involved Leon searching an Umbrella-owned Castle where the T-Virus had leacked. The beta version was more supernatural than survival and shortly thereafter the Beta for Resident Evil 4 became the Beta for the sister series "The Devil May Cry".
