Rusty Key (Outbreak)

The Rusty Key is a special key that is found in the scenario Flashback of Resident Evil Outbreak File 2 on HARD and VERY HARD modes.

Location
The key is found in two different places;

HARD; Room 202, on the bed in front of the door.

VERY HARD; Main Building 2F Hall, hidden behind the broken elevator doors; it requires the Lighter to see.

Purpose
At first, the description reads that it's probably a key to a door in the hospital. The real purpose of it is to remove the cover covering the button in the Administrator's Office, which only appears on the said difficulties.
