Katana Zero is a 2019 platform game developed by American indie studio Askiisoft and published by Devolver Digital. Set in a dystopian metropolis, the neo-noir storyline follows Subject Zero, a katana-wielding assassin with amnesia who can slow down time and predict the future. Zero unravels his past while completing assassination contracts. Katana Zero features side-scrolling hack-and-slash gameplay in which the player attempts to kill all enemies in a level without being hit, using Zero's abilities to manipulate time, dodge attacks, and take advantage of environmental hazards. In between levels, the story is told in sequences where the player converses with non-player characters through dialogue trees.
