Description (written by the developer; not a statement by this register)

Chapter Two is now released! Like for chapter 3! 🧪 Deep beneath the Schell Creek mines, a hidden facility tried to weaponize fear with a hallucinogenic yellow gas. It was meant to harden soldiers. Instead, it shattered minds, twisted creatures into horrific killers, and locked the lab in emergency shutdown. You arrive long after the incident, with 3 Objectives. Override blast doors, purge data centers, burn the evidence of Experiments Y-35 and Y-36, and search for an exit as Yellow seeps through vents and walls. The deeper you go, the less you can trust your eyes. Do you have what it takes to make it out alive? ⚠️ WARNING: Contains jumpscares, intense audio, hallucination effects, and flashing lights. 🎖️ COMMUNITY: Join CHD and follow the creator for rewards, sneak peeks, and future chapters of Operation Yellow. TAGS: Horror, Psychological, Story, Survival, Escape, Lab, Gas, Monster, Thriller, Co-op, Multiplayer, Friends, Scary, Fear
