Core Gameplay: A Dual Game of Puzzle-Solving and Survival

1. Brain-Teasing Puzzles：Explore abandoned laboratories, twisted hospital wards, confined cells and other areas to solve puzzles related to human experiments and architectural mechanisms. From decoding experimental data codes to manipulating outdated power systems to open paths, every puzzle is the key to escape and may hide the terrifying truth behind the experiments.

2. Zombie Shooting：Face a variety of zombies created by failed experiments: the ultra-fast "Experimental Subject - Swift Shadow", the tough-skinned "Experimental Subject - Barrier", and the "Mutated Nurse" that lurks like a ghost. You need to use your weapons and shoot accurately with limited resources to clear a safe path for puzzle-solving and exploration.

Scenarios & Atmosphere: An Immersive Horror Experience

Every corner of the underground building is filled with despair: experimental bloodstains on the faded walls, stopped vital sign monitors, and leftover experiment logs in the cages. Combined with oppressive sound effects and lighting, they maximize the terrifying background of "out-of-control human experiments". You will catch a glimpse of bloodstained remains on a stretcher in the dim corridor, and be trapped by suddenly emerging zombies in a closed room—every exploration is full of unknown terror.
