📋 About This Mod
Patient X
Patient X adds a persistent Mr. X stalker system to Grace’s hospital section, turning him into a full hospital wide hunter rather than a simple model swap, scripted chase or proximity spawner.
He operates through a custom behavior layer built around Search, Investigate and Chase states, letting him react to sight, noise, loss of contact and recovery in a way that I hope feels believable and much closer to RE2-style Mr. X but with a hybrid stealth behaviour to compensate for Grace's different style of gameplay.
Key Features ⚙️
-
[]State-Based Hunting: Mr. X a full state-based hunting system built around Search, Investigate, and Chase, so he no longer feels like an enemy that always knows exactly where you are. He reacts to sight, noise, and broken contact in a way that makes encounters feel more dynamic, more believable, and far less scripted. [/]
-
[]Safe Room Logic: Safe rooms remain functional, with Mr. X being stashed when you enter and reintroduced through delayed off-screen releases when you leave, preventing cheap spawns directly outside the door. [/]
-
[]Spawning & Stealth: Release points are filtered by distance, visibility, and off-screen weighting to reduce obvious pop-in and quieter movement and crouching can help delay or avoid detection. [/]
Requirements:
REFramework with Loose File Loader enabled.

📊 Pros & Cons
✅ Pros
- Community favorite with 239 endorsements and nearly 16k downloads.
- Adds a whole new layer of tension to the hospital section.
- The AI actually uses sound and heat maps, so it feels smart, not just a scripted chase.
⚠️ Cons
- Only affects Grace's hospital section, so if you're not there yet, you won't see it for a while.
- The stalker might be too intense for players who prefer the original pacing.
- Potential compatibility issues with other mods that alter the hospital area or AI behavior.
For Signalis players who want a more terrifying, unpredictable hospital section with a stalker that actually hunts you. If you're a stealth fan or enjoy survival horror tension, this is a must-try. Skip if you prefer the original, more scripted experience or want changes outside the hospital.
💡 Beginner Tips
- Use sound to your advantage: crouch or move slowly to avoid attracting the stalker.
- Learn the safe-room locations in the hospital; they're your only guaranteed breathers.
- Pay attention to the heat map: if you've been running around, the stalker will know where you are.
