Explore the intricate mechanics of Resident Evil 9: Requiem, including health systems, detailed crafting recipes for Grace and Leon, and a breakdown of all difficulty levels.
This guide covers the core mechanics of Resident Evil 9: Requiem, detailing health, crafting, and difficulty settings.
Health
Player health is displayed via an ECG trace for Grace and a ¾ circle for Leon. Health is color-coded: green (500 HP or above), amber, and red (below 200 HP). Grace has 800 HP, expandable to 1200 HP with Steroids. Leon starts with 1200 HP.
A 'mercy' mechanic is in play:
- Grace survives lethal attacks with 1 HP if her health wouldn't drop below -300 HP.
- Leon takes half damage from attacks that would otherwise kill him, though he can still die.
Crafting
Combine environmental items to create ammunition, healing items, and more. Specific recipes and requirements vary between Grace and Leon.
