Final battle dome: (Rebecca and Billy)

Guide to defeating the Leech Queen, the final boss of Resident Evil 0. Learn how to protect Rebecca and use Billy's weapons effectively to win.

Stats / Weaknesses:

• Boss: Leech Queen
• Weakness: Ammo (any kind will do, but some are more effective than others)

Phases:

1. Phase 1: Distraction and Protection

   Rebecca will be busy turning valves. Your primary objective is to keep the Leech Queen from reaching her. Start by using your handgun to distract it. If the Queen starts to target Rebecca directly, switch to the magnum to force it to back off. Keep up this cycle of distraction with the handgun and powerful shots with the magnum when needed.

2. Phase 2: Dealing with Close Encounters

   The Leech Queen is huge and can sometimes run you down, making it hard to see your character. When this happens, make sure you reposition yourself so you can see your character and continue the distraction tactic. Use the magnum whenever it attempts to attack Rebecca.

3. Phase 3: Healing and Completion

   If Rebecca takes too much damage, pause the game and go into your inventory. Select 'Change' and use any herbs you have to heal her. Once Rebecca has successfully turned all four valves, a cutscene will play, and you'll have beaten the game!

Strategy:

• Always keep an eye on Rebecca's status. If she's in danger, prioritize using your magnum to push the Leech Queen away.
• Don't be afraid to use your most powerful weapons, like the magnum, to create distance and protect Rebecca.
• Remember to manage your inventory. If you have herbs, use them to heal Rebecca if she gets hurt badly.
• After the final cutscene, make sure to save your clear file! This is crucial for unlocking hidden content and the Leech Hunter mini-game.
• Consider replaying the game to unlock the hidden guns and explore all the secrets the game has to offer.
