Kathy can be unlocked as a playable character by completing The Hive on HARD difficulty and purchasing her character set for 5.000 points in File #1, and is already unlocked and can be purchased for only 500 points in File #2. Her character set includes Elena, another nurse. She is a Cindy-type character and starts with a Mixed Herb (Green+Blue+Red). On File #1, she is named Nurse1, while in File #2, she is given her proper name, Kathy.
A second version of Kathy also exists that's used for Zombies. This version can only be obtained via gameshark or a similar device and will not have proper stats, making her unable to cause damage and run very slowly. Gameshark codes or codes from a similar device may be used to give her proper stats.
- Kathy is a template for one of the female nurse zombie types in The Hive scenario from Resident Evil Outbreak.
- The Zombie version of her has a large amount of blood near her neck, indicating that she probably had a vital artery punctured by the Zombie that bit her.
