Generation Xth: Code Hazard is a dungeon crawling RPG designed for Windows, marking the beginning of an engaging trilogy. Players can create and customize a party of six characters from a selection of 16 distinct classes, offering a variety of strategic gameplay options. The game challenges players to navigate the treacherous Abyss, where survival depends on careful planning and execution. Notably, save files from this first installment can be carried over to the subsequent game, enhancing the continuity of the gaming experience.

Originally released only in Japan, Code Hazard has garnered attention through a fan translation, allowing a broader audience to enjoy its rich gameplay. The franchise expanded when the first two titles were later re-released on the Playstation Vita, showcasing the game under the titles Tokyo Shinseiroku: Operation Abyss in Japan and Operation Abyss: New Tokyo Legacy in North America and Europe. This accessibility ensures that both new players and long-time fans can immerse themselves in the unique world crafted by Team Muramasa.
