About Degradation: Kyomu's Fury - 劣化:キョムの怒り
Degradation: Kyomu's Fury - 劣化:キョムの怒り is a 3D bullet-hell FPS where you explore a mysterious island while uncovering a hidden virtual network filled with viruses and intense bullet patterns across thirteen chapters with multiple endings. The game stands out for its exploration-to-boss-battle structure, six difficulty modes including a unique MEGA mode, and a narrative about AI and digital friendships rooted in PhD research on logical contradictions in game design.
Summary:
Degradation: Kyomu's Fury - 劣化:キョムの怒り is a 3D bullet-hell/FPS game in which you explore a strange, seemingly abandoned island while discovering its hidden, vast virtual network. Fight viruses, survive insane waves of rays and bullets, and find out more about the inhabitants of the Network.
Some overall primary features:
- Up to thirteen chapters and three possible endings.
- A variety of locations, alternating between short exploration and boss battles.
- 6 difficulty modes, including a practice mode, and a "MEGA" mode with unique enemy attack patterns, best suited for a second playthrough.
- A light story about AI, viruses, and making new virtual friends!
Gameplay considerations
- The game can be played with a controller, but a keyboard and mouse setup is recommended.
- DLSS is available.
- Realtime ray/path tracing is necessary for some of the effects used in the game. Thus, a GPU capable of handling this type of rendering is required.
Bonus content:
- A game not previously released on Steam, titled World Annihilation Operations: Space Manipulation. It showcases various sci-fi and surreal environments in which space seems unstable. From impossible objects, to teleportation portals, or multiple depths of reflections, explore 5 levels of weird visuals while occasionally solving environmental puzzles.
- A second much smaller game, never released anywhere, developed in the context of a game prototype design class a few years ago. It is a simple platformer game set in a long tunnel where gravity works in mysterious ways.
- A music player, letting you listen to the music found within the main game, at your own leisure.
Academic context:
This game (as well as the first bonus game) is done in the context of a PhD research on the integration of logical contradictions in video game fiction. It is expected that more games emerge from this research. Following the publication of these works, the operations developed through the creation process should lead to the development of one much larger adventure game in the coming years.
This game is entirely free. If you would like to support the developer, please consider purchasing one of the DLCs (they do not add any content not accessible within the game!).

What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Degradation: Kyomu's Fury - 劣化:キョムの怒り is praised for its challenging boss fights, striking neon visuals, and engaging blend of bullet hell and FPS mechanics, though players consistently note that the music is unremarkable and the game demands significant hardware to run smoothly without frame rate issues. The intense visual effects can cause performance problems even on lower settings, so players should ensure their computer can handle it before purchasing.

My gambling addict friend said if I post a review on Degradation: Kyomu's Fury - 劣化:キョムの怒り and it gets 350 likes and 150 Awards that he will buy me a case of beer and some vodka . So I'm just gonna leave this here.2 found this helpful
This is a pretty good game. Great boss fights, great visuals, and a nice challenge. My one thing is the music. It's very... interesting to say the least. Other then that a really good time. Check it out if you're into Bullet Hells or FPSs.1 found this helpful
WOW, this is a test of your eyes ability to be under max load at all times. It feels like they might start bleeding from the cutting edge neon glow, I only wish my computer was better so it ran smoother and I could blame my loosing on myself and not the frame rate drops and input lag. I love it, Just make sure your computer can handle it. even on the lowest settings, both my eyes and computer were about to start beeeling out. Its like a room with a boss and a bullet hell dodge fest. trippy visuals and even trippier graphics, meh music though.
