Setting

The world of High-Rise Invasion consists of an expansive, artificial realm composed of countless skyscrapers interconnected by precarious rope bridges and scaffolds, extending endlessly without any visible ground below, evoking profound isolation and vertigo. This environment is accessed via enigmatic stairs that abruptly transport individuals from the real world into this vertical labyrinth, where urban structures from reality are replicated but devoid of normal societal functions. The realm operates under strict, game-like rules designed to perpetuate a cycle of survival and selection, with the overarching objective of producing a "Perfect God" to govern the world by enforcing its structure and protocols. Masked figures, referred to as Hunters or Angels, are central to these mechanics; these entities are humans reprogrammed by technological that interface directly with the brain, compelling them to eliminate non-candidates or convert suitable individuals into God Candidates through neural code installation. Observers serve as passive monitors within this system, while Hunters actively enforce the kill-or-convert directive to maintain the realm's deadly equilibrium. Key mask types define the system's hierarchy and functions: Smiling Masks, the most prevalent Angels, execute commands promoting despair, , or to cull participants; Angry Masks, or , defend the realm's integrity and only engage lethally when provoked; Emotionless Masks facilitate neutral interactions by distributing supplies without aggression; and Faceless Masks initiate a 10-minute sequence upon attachment, embedding code that transforms the wearer into a God Candidate capable of manipulating compatible masks based on wavelength alignment. God Masks, worn by candidates, position them as potential rulers with enhanced control over the environment, while specialized controller masks sustain the cycle by directing overall operations. Escape from this domain hinges on rare opportunities, such as intercepting a daily patrolling that lands at random or advancing toward the central main tower, though success demands navigating the constant threat of masked assailants. Accumulating Faceless Masks can also disrupt the programming for candidates, potentially granting leverage against the system. The artificial construct of the world amplifies psychological strain through enforced isolation, breeding as trust erodes amid the ever-present risk of hidden masks among survivors, compounded by surveillance mechanisms like administrative oversight and aerial patrols that ensure compliance.
