Resident Evil Requiem Simulates Heart Rate, Fear and Sweat

Capcom has revealed new technical details about Resident Evil Requiem, highlighting how the game uses dynamic systems to simulate characters' heart rates, fear levels, breathing, and sweating.

The details come from a developer feature in the November 2026 issue of Japanese computer graphics magazine CGWORLD, which explores the technology behind the game's realistic character animations.

According to the CGWORLD report, Resident Evil Requiem uses an internal heart rate parameter that changes based on physical activity, including running and other movements.

A separate fear parameter tracks characters' reactions to threatening situations. Together, these systems influence breathing patterns and animations, helping characters display more natural responses to danger.

Capcom also developed systems that control sweat, moisture, and dirt on character models. Clothing features three levels of accumulated dirt, reflecting different stages of the adventure.

Another notable detail involves wet clothing. When characters leave a wet environment, their clothes gradually dry rather than immediately returning to their original appearance.

This process continues during cinematic sequences, allowing the game's visual state to remain consistent between gameplay and cutscenes.

The development team also focused on persistent blood effects and visible injuries. Marks left during encounters can remain on characters and environmental surfaces, while the visual effects team worked with character artists to create varied enemy appearances.

These systems build on Capcom's earlier efforts to portray fear through subtle physical details, particularly in protagonist Grace Ashcroft.

Resident Evil Requiem launched on February 27, 2026, for PC, PlayStation 5, Xbox Series X|S, and Nintendo Switch 2, using Capcom's RE Engine.
