Katana Zero Review and Why Its Rewind Story Hits Hard
You die in one hit, the screen rewinds like an old VHS tape, and a calm voice tells you that plan would not have worked. Ten seconds later you clear the room in a blur of deflected bullets and a single sword swing.

You die in one hit, the screen rewinds like an old VHS tape, and a calm voice tells you that plan would not have worked. Ten seconds later you clear the room in a blur of deflected bullets and a single sword swing. That loop is the heart of this Katana Zero review, and it is why a game you can finish in about five hours still gets talked about years after its 2019 release.
I came back to it recently on Switch after first playing it on PC at launch. It holds up better than I expected, with one or two caveats worth knowing before you buy.
What Katana Zero Is
Katana Zero is a 2D action platformer from the small studio Askiisoft, published by Devolver Digital. You play Zero, a sword-wielding assassin in a neon-lit city who takes jobs from a psychiatrist. Before each mission, the psychiatrist gives him a dose of a drug called Chronos, which lets him slow time and, as the story frames it, see the future.
That framing is clever. Every death is not really a death; it is Zero imagining a plan that fails. When you finally clear a stage, the game plays back your successful run at normal speed, like security footage. Watching yourself cut through a hallway in four seconds flat is an excellent reward, and it never got old for me.
The game is available on PC, Nintendo Switch and Xbox, and usually sells for around 15 dollars, often less on sale.
Katana Zero Review: How the Combat Feels
Everything dies in one hit, including you. That rule shapes every room. A guard with a pistol, a shotgun enemy behind a door and a turret on the ceiling form a small puzzle you solve with movement, timing and your sword.
Your toolkit is small but tight:
- A sword slash that kills instantly and, timed right, reflects bullets back at whoever fired them.
- A dodge roll with brief invincibility, useful for slipping through lasers or past a melee swing.
- Slow motion on a meter that refills quickly, so you use it often rather than saving it.
- Throwable items such as bottles, knives and smoke grenades scattered through levels.
Bullet reflection is the standout. The first time you slice a shot back into a gunman across the room, the game clicks. By the midpoint, you are chaining reflections, rolls and doorway kicks in ways that feel improvised even though you have rehearsed the room six times.
Restarts are instant, which matters. A failed attempt costs you two or three seconds, never a loading screen. That keeps frustration low even in rooms that take 20 tries.
The Story and the Interrupt System
Most action games treat dialogue as a break between fights. Katana Zero turns it into another test of timing. During conversations, you can often cut someone off by responding while their line is still appearing, marked by red text options. Interrupting changes how characters react to you, and in some scenes it changes what happens next.
A receptionist early on is the best example. Be polite and patient, and the scene plays one way. Cut her off repeatedly, and you get a very different outcome. These moments make Zero feel like a person with impulses rather than a blank avatar.
The story itself is dark and fragmented, dealing with war crimes, drug dependency and memory loss. It hints more than it explains, and you will likely end the game with questions. Some players love that. Others find it unfinished, which leads to the main criticism.
Where It Falls Short
Here is the honest part. The game ends on a cliffhanger that sets up a clear second act, and for a long time that continuation was promised as a free expansion that kept slipping. If you need a story with a complete resolution, you should go in knowing it stops short. I would still recommend it, but the ending can feel abrupt when you are most invested.
The length is the other talking point. Five to six hours for a first run, closer to four if you are quick. I think this is fine, and I disagree with people who call it too short. The game respects your time and never pads a stage. A 15 hour version would almost certainly repeat ideas, and the tight design is exactly why replaying stages to improve your time is so satisfying. Still, if you count hours per dollar, know what you are paying for.
A few later levels also lean on trial and error more than reading. A sniper beam or a surprise enemy appears with little warning, and you only learn it by dying. It is not common, but it stands out against the fairness of earlier stages.
Music, Art and Feel
The synthwave soundtrack, composed by LudoWic and Bill Kiley, is excellent. Each stage starts with Zero putting on his headphones, and the track that kicks in sets the pace for the run. Several songs are worth listening to outside the game.
The pixel art is detailed and full of small animations: shell casings, blood splashes that stay on walls, flickering neon. Effects like the VHS rewind and screen glitches during Chronos withdrawal are used sparingly enough that they stay effective. Like the stylised underwater gloom in our Dredge review, the visuals do real storytelling work rather than just looking good.
Who Should Play It
Play Katana Zero if you like fast action where each room is a small puzzle, enjoy replaying sections to get them clean, and do not mind an unresolved ending. It is a strong pick for anyone who enjoyed the precise movement in Ori and the Will of the Wisps but wants something shorter, harder and grittier.
Skip it, or wait for a sale, if you need a long game or a complete story arc, or if violent content and themes of addiction are something you would rather avoid. The game is rated for mature players for good reason.
My verdict: an 8.5 out of 10. One of the most confident small action games of its generation, with combat that still feels sharp years later and a story that leaves you wanting more in both the good and the frustrating sense.
FAQ
How long does it take to beat Katana Zero?
Most players finish the main story in about five to six hours. Skilled players can do it in four. Speedrunners and players hunting hidden content will spend much longer.

No, the story ends on a cliffhanger with several threads left open. A continuation was announced but has taken a long time to arrive. Go in expecting the first part of a larger story.

At around 15 dollars, it is good value for a polished, replayable action game. If you prefer long games, wait for a sale, as it is discounted often. The quality of each hour is very high.
