Some time in the future, you control an unnamed modern mercenary samurai, known by your enemies as dragon. Contracted by mysterious people to kill certain targets, you slowly realized that there's more behind to this job and the mysterious powers that you possess. A simple story, but told in kind of convoluted way. The game works like a puzzle game where you solve the problems choosing meticulously the proper movements. Which means being fast and lethal in the right way, like a choreographer of death. The one hit death mechanic makes the action always seems impactful and urgent. An excellent pixel art translates the violence and mood really well. Katana ZERO is a nice little gem, unique and real fun.
