Operation Abyss: New Tokyo Legacy is a sci-fi dungeon crawling RPG that takes place in near-future Tokyo. With the city under the constant threat of Variants - genetically engineered monsters - and the emergence of portals leading to a mysterious dimension called the Abyss, the government has established a secret organization called the Code Physics Agency to investigate these mysterious phenomena. Operating under the guise of a private school called Hinowa Academy, the CPA recruits teenage youths to be part of the "Xion Transhuman (Xth) Squad." The CPA uses their Code technology to provide the Xth Squad with "Blood Codes", special Codes that contain the genomes of history's greatest heroes and bestow the Xth Squad with powerful abilities to combat the Variant menace. Using a team of six people, the player will map dungeons, evade traps, and face powerful monsters as they investigate the mystery behind the Variants and the Abyss.

Robust Customization System - Recruit and train a unique group of six Xth members to venture into the Abyss. Customize each member from one of ten distinct Blood Codes. Each Xth member's appearance, class, personality, morality, and stats may be molded to the player's preference. An Accessible, Yet Deep Dungeon Crawler - The labyrinthine dungeons of New Tokyo offer 40+ hours of dungeon crawling action with traps, secret doors, challenging enemies, and gorgeous art throughout. A Unique Sci-Fi Story - Dive into the unique dungeon-crawling setting and lose yourself in its gorgeous world, featuring real-life locations rendered by Tetsu Kurosawa and Oxijiyen. A gripping story blends heavy sci-fi elements with tense dungeon-crawling to keep you delving ever deeper into the abyss. Languages - Enjoy English in-game text and English & Japanese in-game voices.
