That was pretty much the second half of Cold Fear that you described right there.

Resi has gone about as far as it can go with unique and new features of areas: creepiness of the mansion (Resident Evil/0), Raccoon city (Resi 2, Resi 3, Resi Outbreak), Central American prision island (Code Veronica), tropical holiday island (Survivor), Arctic (Code Veronica), Boat or Crusier (Dead Aim), Spain (Resi 4), Africa (Resi 5), research facilities (all of the above).
