This chapter takes Leon and Helena through ancient catacombs beneath Tall Oaks. The environment is dark and filled with traps. You'll encounter new enemy types, including the Shrieker, a zombie that emits a sonic scream, attracting more enemies. Prioritize taking them out quickly. There are several environmental puzzles involving levers and pressure plates. Work with Helena to activate mechanisms. Be prepared for a segment where you're separated from Helena, requiring you to navigate a section alone. The chapter culminates in a confrontation with a mutated creature in a large chamber.
