Inside of BIO-HAZARD, otherwise known as the "BIO HAZARD Perfect Guide", is a 144-page guide book for the original Resident Evil, published in 1997. It includes a very novice-friendly navigation guide using the maps, and reveals interesting additions to the game's backstory.


File 1 (p.6-34)

Inside of BIO-HAZARD - page 11 (Forest)

An example of the S.T.A.R.S. profiles.

File 2 (p.34-58)

This section includes a large description of the Clay virus, the predecessor concept to the "Progenitor Virus" in the franchise's earlier years. Each entry on B.O.W.s indicates what variant of the virus they were infected with as a bonding agent, with the zombies also being mentioned as being infected with the "ε" (epsilon) strain.

The section then moves on into an analysis of each creature seen in the game, with various notes added in. The crows encountered in the game are referred to as "jungle crows" (ハシブトガラス hashibutogarasu?), a common East Asian bird species similar to ravens. They are revealed to have been infected by consuming the zombies' rotting flesh. The wasp enemies are revealed to have been infected by consuming the pollen of Plant 42, explaining why they reside in the dormitory.

The T-002's internal biology is also brought up, revealing it to have a tricardialpulmonary system (using three hearts).

File 3 (p.59-122)

The third chapter ends in a page covering the estimated casualties resulting from the Mansion Incident, including Umbrella's human test subjects killed during the S.T.A.R.S. investigation. It totals to around 128 individuals.

  • Seven members of the S.T.A.R.S. investigation teams are listed as deceased. Since this is before the 2002 remake's retcons, RPD pilot Kevin Dooley is not mentioned.
  • The numbers of casualties from the mansion and dormitory staff is given as approximately forty-six. Most of the infected are killed during the S.T.A.R.S. investigation, though at least one suicide can be confirmed through documents lying around.[excerpt 1]
  • An estimated number of twenty-five members of staff in the laboratory is recorded. The staff in the laboratory are described as having committed suicide more often than those in the mansion. It is suggested that they learnt of the viral leak early on and were prepared to take their lives.[excerpt 2]
  • Seven staff members on temporary transfer from Umbrella HQ are listed independently; the possibility that they were quarantined instead is raised. It is also brought up that their identities may be hard to identify.[excerpt 3]
  • Twenty-two B.O.W. test-subjects were also of human origin, suspected of having been taken from lifestyles with nonspecific residence such as the homeless community. As a result, the book notes that these victims would be extremely difficult to identify. Most of these subjects were killed during the S.T.A.R.S. investigation.[excerpt 4]
  • The T-002's former, human identity was left impossible to confirm due to the damage its body sustained during the battle and resulting explosion.[excerpt 5]
  • Approximately thirteen people of four households are marked as victims of the escaped dogs and zombies.[excerpt 6]
  • A final seven or so out-of-state hikers/mountain climbers were also attacked by the Cerberus pack. All but two went out hiking alone.[excerpt 7]
