01//Briefing
You are Zero, a hired killer who gets his targets from a psychiatrist and his medication from the same man. Each level is a contract: clear the building, then watch the replay as if it were a security tape. Between jobs you go back to a run-down apartment, talk to a neighbour's kid and slowly realise how little you know about your own past. The story is told in fragments and it is better the less you know going in.
02//In the field
Everything dies in one hit, including you. You dash, slash, deflect bullets back at their shooters and throw objects, with a short slow-motion meter to plan the room. Death restarts the section instantly, framed as Zero imagining what will not work before he does it. The controls are tight enough that every failure feels like your mistake, which is what makes the many quick retries satisfying instead of annoying.
03//The city
The world is a neon, rain-soaked city rendered in detailed pixel art, with a synthwave soundtrack that plays from Zero's headphones at the start of each level. You do not explore it so much as pass through it in vivid set pieces: a nightclub, a mansion, a prison, a motorbike chase. It is small, but every location is distinct.
04//Systems & choice
The dialogue system is a quiet highlight. You can interrupt people mid-sentence, which changes how they react, and some choices echo much later in surprising ways. There is no levelling or loot, and the action stays the same tight loop throughout. A hard mode unlocks after the ending, and so do extra weapons you can find on a second run.
05//On your rig
It runs on almost anything and is Steam Deck Verified, where it plays perfectly with the default controller layout. A controller is optional: keyboard and mouse aiming for the slash works well. Expect five to seven hours for the story and more if you chase the hidden content.

FINAL VERDICT
Katana ZERO packs more style, tension and narrative surprise into six hours than most games manage in sixty. The one-hit combat is demanding but fair, and the story will stay with you. The best value on this chart.
