■ Game Overview

"Your choices will rewrite your knowledge."

To unlock the full capabilities of the BMI-based investigation support prototype "ADA," Officer Mutsumi Rokkaku dives into the virtual world "B2." Your mission: reach the 100th floor and defeat the Guardian waiting at the summit, all while constantly upgrading your systems. Faced with ever-changing situations, masked enemies, and cunning traps—can you use logic and luck to conquer this "Virtual Hell"?

■ Key Features

1. Three Doors of Destiny

Every floor presents you with three doors. Each door is assigned different growth parameters that change randomly with every run. Which stats will you prioritize? That single decision is the only path to the 100th floor.

2. Ever-Evolving "Once-in-a-Lifetime" Strategy

The tools and equipment you find along the way change their form with every dive. Will you brute-force your way through with powerful gear, or use specialized tools to bypass deadly traps? No two runs are ever the same. Your wisdom and experience are your ultimate weapons.
