Puppet Cybil Bennett is a major boss in Silent Hill.
Cybil Bennett becomes possessed after being attacked by the same parasite as the Puppet Nurse and Puppet Doctor. Cybil appears in Lakeside Amusement Park's Merry-Go-Round, sitting in a wheelchair, but stands up when Harry Mason enters. Killing her will result in the Good or Bad ending, while saving her will award the player with the Good+ or Bad+ ending.
Cybil walks slowly after Harry. She is capable of shooting him with a handgun that will instantly take the player's health to red, showing that she is very dangerous. Once she runs out of ammo, she will then put down her gun and walk to Harry in an attempt to strangle him.
If Harry runs around the carousel, she can be seen sitting on one of the horses and will jump off once Harry approaches her.
The best strategy to kill Cybil is to get her to run out of ammunition first; it takes less than 10 shots to get her to drop her handgun. If one attempts to shoot her before she drops her handgun, there is a high risk of getting shot at in the process, due to open position and Harry's recovery time from the firepower. To avoid Cybil's fire, strafe left or right, or run around her in a circular motion. If Harry is hit, it is best to immediately heal. She can also pistol-whip Harry if he is too close; this does not inflict a tremendous amount of damage, but being within close proximity of her and continuously receiving this treatment does accumulate dangerous wounds.
Once Cybil drops her handgun, equip the handgun, shotgun or Hyper Blaster, but never the rifle as Harry cannot move while using it. Shoot Cybil with the firearm and walk backwards at the same time. If Harry gets caught on a horse while walking backwards, turn around and move further down the carousel. Because Cybil walks faster than Harry walking backwards, it is recommended to turn around and leave more distance between Harry and Cybil when she comes too close. To quick turn, press the L1 and R1 buttons at the same time.
