The mechanical warning klaxons blared a rhythmic, deafening echo through the massive, enclosed space of Ground Beta. Towering concrete skyscrapers had been rigged with high-grade hydraulics, groaning and shifting violently to mimic a hyper-realistic, post-collapse urban disaster zone. Heavy plumes of gray dust and debris clouds swept through the narrow alleys.
Standing on a buckled asphalt road in the dead center of the simulation block, U.A.'s newly formed covert tactical squad waited beneath the watchful eye of their pro-hero mentors.

He projects his voice over the simulation's loudspeaker system from the high control booth Listen up. The real world doesn't offer neat, organized tournament stages. You are an underground wildcard unit. Your objective is simple: navigate the shifting ruins, locate the structural weak points, and survive the guerilla ambush. If you drop your coordination for even a split second, you're expelled.
