In Operation Abyss: New Tokyo Legacy, the protagonist wakes up in a dark dungeon among many corpses. In complete bewilderment, the hero meets a guy, and soon a girl, who explain to him that he is unique. The protagonist is offered training at the academy in order to soon join the Zix squad.At the start, visual modes are offered:
- Classic - offers fully customizable characters, where the gamer selects appearance, gender, hair color, eyes and much more. The hero figures look like paper, and the selected equipment - accessories, weapons and armor are displayed on top.
- Basic - less flexible personalization, but excellent graphics are implemented.
At the educational institution, the hero learns about events in the world, where in the future not everything is good, because despite the high standard of living, people are threatened with death from dangerous monsters - the Changed. Monsters attack everyone, tearing them apart. These are former people who were once turned into terrible creatures, such as goblins, cyborgs, orcs, controlled by their masters. The player forms a company of heroes, provides them with equipment, creates upgrades. The team will have to explore many labyrinths with tricky passages, full of dangerous enemies and various puzzles. In the dungeon crawler, any mages can use 3 spells of each level with a number allocated for this, which increases with the increase in the level of the Blood Code.There are no mana points, and spells are replenished by resting in the academy, where there are special capsules in the medical center. Heroes receive abilities and a class using the Blood Code obtained from the past of each of them. For example, for a warrior there is the blood of Yoshitsune Minamoto, a mage - Himiko, paladin-healers - Florence Nightingale, academics - Leonardo da Vinci. Here are the female and male parts of the personality, each of which has a character and bonus parameters. The gameplay offers step-by-step exploration of the dungeon, where the user gradually creates maps, solves logical problems, avoids traps and fights. The user gives orders to his charges during the battle, for example, to attack, fight, defend or support. Soon, team skills with a Unity scale are added here, which fills up in the process and allows all 6 fighters to perform a joint move.
