Katana Zero is a 2D action platform video game developed by Askiisoft and published by Devolver Digital for Microsoft Windows, macOS and Nintendo Switch in 2019. The game was also released on Xbox One on October 15, 2020 with a free DLC planned for 2021.

Katana Zero includes no health bar and being hit will result in instant death. The player character navigates side-scrolling levels, attempting to kill all enemies in that level using his blade or environmental traps. The game also features a real-time conversation system that the player can interrupt.

Katana Zero takes place in the dystopic, neo-noir metropolis of New Mecca. The game's plot is heavily affected by an invasion of an unnamed Asiatic nation, referred to as the "Cromag War," New Mecca's faction is implied to have lost the ensuing conflict.

The player controls a katana-wielding assassin called Subject Zero, as he completes various assassination contracts given to him by his psychiatrist, who also supplies him with ‘Chronos’, a drug that allows him to slow down time and predict the future.

Subject Zero (Katana Zero) has not been a contender in any CBUB matches.
