Paris: Liminal Pursuit

A solo, two-window mashup prototype for Assassin's Creed Unity and Escape the Backrooms. Unity actions send a local threat signal to the Backrooms game. The companion mod is designed to scale the existing Bacteria AI's hearing range while leaving its pathfinding and player controls alone.

Controls

• Ctrl: Unity's default stealth toggle. While stealth is on, threat falls.
• Shift + WASD: parkour movement raises threat quickly.
• WASD: ordinary movement raises threat slowly.
• Left mouse: attack raises threat in a short pulse.
• F8: mashup cue for a guard fully detecting Arno. This cue is manual; the game does not expose guard-alert state through a supported mod interface in this build.
• Switch focus to the Backrooms window and evade its native entities. The mod only changes the Bacteria AI's sensing range.

Package layout

The archive is laid out for Escape the Backrooms' Binaries\Win64 folder. Its UE4SS runtime is the EscapeTheBackroomsCommunity v1.3.0 fork; its MIT license is included. The UE4.27 engine override and safe hook settings follow the game's maintained HostKit compatibility notes. No game assets or ACUFixes files are included.

Melty starts ParisLiminalPursuit\ParisBridge.exe and passes it both installed game folders. The bridge opens both Steam games, then shows a small threat meter while it runs. Steam must already be signed in. It stores only the latest PLP1 snapshot in the Backrooms mod folder and never contacts a network service.

Verification status

• The bridge executable's self-test passed for parkour threat, stealth decay, the manual alert cue, and snapshot serialization.
• The Escape the Backrooms asset index contains the Bacteria AI controller and the two PawnSensing threshold properties used by the receiver.
• The previous diagnostic-only UE4SS probe loaded in the installed Backrooms process. The final receiver has not yet been observed changing a live Bacteria actor during gameplay.
• This desktop session could not interact with the game windows, launch both Steam games, or capture real gameplay media. The Melty listing therefore remains a draft until those checks pass.
