Operation Babel: New Tokyo Legacy is a sequel to the Japanese-style first-person role-playing game. The game continues the story told in Operation Abyss: New Tokyo Legacy and will once again send you on missions full of danger, accompanied by numerous battles with monsters from another dimension. An unusual object, called "Embryo", suddenly appeared in the sky above Tokyo. Of course, the UAW organization could not sit idly by and watch the outrage taking place, so the Zix detachment was again assembled, consisting of both veterans of the unit and newcomers. Now the squad’s fighters are even more capable than before, because a new “sub-blood” system has been developed in the depths of the laboratories, allowing the creation of hybrid classes, and the possibility of improving the characteristics and abilities of characters using modifiers has also been opened.
