Katanaut Review

Imagine being imprisoned on a wrecked space station where the only noises are the synthwave music booming through the steel halls and the sound of your sword cutting through the air. Void M is the lone person who produced Katanaut, a Metroidvania game that also functions as an indie roguelike.

It takes the intensity of Katana Zero and the creepy atmosphere of Dead Space, turning them into a cosmic horror playground where you must be skilled, precise, and stubborn enough to keep trying after every death.

Katanaut isn't just another roguelike where you have to "run one more time." It is a bloody, fast-paced, and stylish mix of high-speed swordplay and Lovecraftian nightmares, all set against a backdrop of pixel-perfect sci-fi horror. If you like games that punish mistakes and reward skill, this is one you should keep an eye on.

Katanaut has been in the works for over three years, with most of its development handled by just one person. It's easy to see where the ideas came from: Dead Cells for its smoothness and progression, Katana Zero for its sharp style and pacing, Ninja Gaiden for its hard-to-master combat, and Dead Space for its creepy atmosphere.

Katanaut never feels like a copy, even though it proudly wears these influences. Instead, it creates its own identity by combining the unpredictability of roguelites with hand-crafted details that make each hallway feel alive—or maybe more accurately, broken. This game exists because someone loved these ideas enough to put them all together, not because a committee made the decisions. You can tell because every hallway and room is full of details.

You are Naut, a futuristic ronin samurai who boards a space station with a small crew. When you get there, you find that almost everyone has turned into a monster. As you go deeper into the station's heart, the enemies you fight become less human and more monstrous. They transform from corrupted workers into monsters resembling entities from a cosmic horror nightmare. 

There aren't any long cutscenes or a lot of exposition in the story. You learn by piecing together information, such as logs left in dark corners, dialogue snippets, strange rooms, and even the enemy designs themselves. Every run gives you another clue about the bigger mystery, and the promise of better loot is just as strong as your curiosity.

This simple way of telling stories works because it keeps you on edge. You are never told everything directly, which is why the unknown itself makes you scared. The more you push, the more you wonder what happened on the station and what lies at the bottom.

Speed and accuracy are what Katanaut is built on. Combat is quick and sharp, with jumps, wall-kicks, dodges, and slashes happening right away when you press a button. Your primary weapon is the katana, but it's not just one blade. Different katanas let you play in various ways.

The dash katana is dangerous and aggressive; each swing propels you forward, allowing you to cut through enemies like a pinball bouncing around a room. It feels great, but missing an enemy or sliding off a platform can end the run right away. The parry katana, on the other hand, rewards those who are patient and know when to strike.

Enemies show you their attacks with a flash, and if you parry at the right time, you can counter with a powerful attack. More runs unlock even more variations, so combat never gets boring. You can equip off-hand tools and guns, from pistols to plasma rifles, in addition to the katana. Each one gives you different tactical options.

You have two active skills to round out your kit. These skills include brutal dash attacks, ground smashes, and even effects that slow down time to give you a temporary edge when you're surrounded. You have to think a lot about all of these mechanisms that go into a stamina meter.

You have to pay for every shot, slash, and dodge, so if you click the buttons too hard, you'll run out of money quickly. In the end, the battle is like a fast-paced dance where you have to make quick choices, keep time, and stay in sync. Katanaut doesn't have traditional puzzles, but it does make combat situations that feel like puzzles in their own right.

Elite enemies spawn with mutators that alter the shape of other enemies around them, creating chaotic rooms until you destroy their altar. Some parts of the game require you to figure out how to control the swarm before getting trapped, while others have you navigating tight platforms that challenge both your swordplay and movement skills.

Boss fights take this to the next level. Each one is a different challenge that will help you change your habits and learn to adapt. Some punish being too aggressive, while others reward taking risks at the right time. For instance, the second boss teaches you that using space and skills is better than just slashing all the time. The game's strange "cat system" even hides optional bosses behind it.

While you're running, stray cats show up. If you pet them, they sometimes turn into hidden bosses that are both funny and deadly. Regular mobs, elites, and bosses keep the fighting interesting. It's not just about reflexes; it's also about making decisions and planning, which keeps the action from being mindless.

Katanaut is a good roguelite because it gives you a sense of progress even when you fail. When you die, you return to the hub, where you can collect memory fragments and resources to unlock new upgrades. These pieces are the building blocks of growth. They allow you to acquire more weapons, improve your skills, and try out new abilities.

Implants add another layer and give you powerful buffs, but you have to be careful how you use them because there isn't a lot of room. Syringes found in the middle of a run give you short-term health, stamina, damage, or ammo boosts that can help you survive a tough room.

Two different currencies are linked to progression. You can use purple orbs to permanently upgrade items, such as unlocking new implants or increasing your maximum health. You can also spend gold on weapons and temporary perks during runs. This split prompts you to consider both the short-term survival of your current run and the long-term growth that will aid you in future attempts. You get something that makes the next try more likely to work, even if you only clear a few more rooms before you die.

Katanaut's pixel art style is the perfect mix of old-school charm and modern sharpness. The hallways are filled with numerous details, including blood on the walls and lights that flicker and pulse with fear. Enemies come in different shapes, so it's easy to tell them apart even when things are crazy. The violence is too much, but it's always easy to understand. Every slash feels good because of the blood sprays and screen-shaking feedback.

The most interesting thing is how the station changes as you go down.  The first parts look like empty factories, but as you go deeper, they change into something strange and creepy that makes it hard to tell where steel ends and flesh begins. The more you look around, the more the places seem to come to life and be affected by Lovecraft's work. As a result, the world is dark, scary, and hard to forget. 

One of the best things about Katanaut is the music. The action is set to driving dark synthwave beats that match the fast pace of the fighting. The music isn't just background noise; it intensifies the fight by making you move faster and hit harder.

The sound design goes perfectly with this. The sound of every katana clash is heavy, the sound of every gunshot is loud, and the sound of enemies screaming is deafening. The music and sound effects work together to make the station feel like a dangerous, living place. This audio design isn't subtle at all; it's loud, violent, and stylish, and it fits perfectly with the gameplay.

The fighting in Katanaut is the best part. The combination of quick sword fights, strategic choices, and roguelike unpredictability makes it hard to stop playing. There are so many weapons, skills, and implants that no two runs feel precisely the same. The game strikes the right balance between being hard enough to punish you and giving you rewards for growing, thanks to its strong progression system.

The music and art create a unique mood that stays with you even when you aren't playing. Katanaut does a great job of making you feel like you're in a real place, which is rare for indie games. Boss fights and secret encounters add levels of surprise that keep you interested, and the overall design makes every win feel earned.

The game does have some rough spots, though. When you're platforming, the dash katana's momentum can make you slip, and sometimes loot drops pile up in a way that makes it easy to grab the wrong one. The difficulty curve is steep, which is part of what makes it fun, but it might turn off people who like Metroidvania games that are slower or more forgiving. These problems don't ruin the game, but they do show where polish could make an already strong base even better.

Katanaut is a brutal, stylish, and atmospheric roguelite. It doesn't just copy its inspirations; it makes them into something new. It combines the accuracy of sword fighting with the unpredictability of roguelite design and adds cosmic horror that drips from every pixel. You learn something new from every death. Every win feels like it was hard work. And every run pulls you deeper into a station that is both scary and beautiful.

Katanaut is a must-try for fans of games that demand quick reflexes, keep you on edge, and reward perseverance. The game is worth playing whether you want to learn how to parry perfectly, dive headfirst into dangerous dashes, or explore its creepy hallways in search of answers.
