Resident Evil: The Umbrella Chronicles's room configuration for some buildings are exact copies of Outbreaks, rather than main series (i.e. R.P.D. Car Park follows Outbreak's dimensions, not 2's even though this is which its based on). Also, locations such as the Apple Inn, J's Bar and a few other buildings from the Outbreak series are shown in the Resident Evil 3 sections. In each stage, there are sometimes multiple routes which you can take, which encourages players to replay the levels so that you find every file, and get a better rank.
