PROPDAY Wiki
Mechanics
Transformation, movement, physics, detection, and survival fundamentals.
Transformation
Survivors take the form of nearby objects. A chair, crate, or lamp can become a hiding place. An outline shows when an object can be transformed into.
Movement & physics
PROPDAY is built with Unreal Engine 5.7, featuring a custom physics system designed to make every movement, collision and sound feel realistic, responsive and satisfying. Every detail has been carefully refined over months of development to deliver a high quality gameplay experience.

Physics development
On October 21, 2026, Davy confirmed that A–D movement responsiveness had been improved, making side-to-side direction changes easier to control. He also announced the start of a transition to NVIDIA PhysX for friction and other parts of the physics system, aiming to improve prop weight, surface resistance, and player control. The transition is in progress, not confirmed as complete; earlier physics preset information may change.
Prop controls
In prop form you can jump twice, with an extra jump close to the ground. Jumping in human form is temporarily disabled, as confirmed during the October 18, 2026 playtest. Press X to switch the camera between left, right, and center. Collision sounds scale with impact speed and object weight. Jumping as a prop makes a sound nearby players can hear, and transformation effects are visible to everyone.
Terror radius & chase
The killer carries a terror radius: survivors inside it hear the chase build up, and chase music kicks in when the killer is on someone's trail.
Random spawns
Generators, exit points, coins, and loop obstacles spawn at randomized locations every match, so no two trials play out the same way.
Looping & obstacles
Survivors loop obstacles to keep distance from the killer. Once an obstacle is passed, it blocks the passage for 1.25 seconds.
Detection & survival
The killer looks for suspicious details in the environment. Survivors must stay hidden while working toward their escape.
