About Project Arrhythmia

"Project Arrhythmia" is a musical bullet-hell in which all things beautiful are deadly. A cacophony of lights, music, pulses and blocks, Project Arrhythmia features tight bullet-hell style gameplay where up to 4 players in local co-op must navigate their way through evolving scenes and obstacles, all timed to the beat.

STORY

Set in 207X, a mysterious disease called "LNNS" has been ravaging the world. A lone AI researcher, Anna Schroeder, attempts to find the cure with her trusty supercomputer companion HAL. Stumbling upon various “Projects,” the duo decides to investigate the efficacy of a cure using a pulse/rhythm-based interface. Work in progress.

CURRENT FEATURES

  • Dodge The Beat: Stages consist of mesmerizing, musically timed scenes, each one telling a story. Feel the rhythm and feel your way around the hazards! Anna will judge how you do.

  • Challenge Your Friends: Up to 4 players supported in local co-op mode.

  • Robust Level Editor: A carefully designed level editor allows users to create their own levels and challenges using whatever music they wish.

  • Huge Community: A Wealth of user-created content exists, fully integrated into the game through the usage of the level editor and user-made levels. Already, 2000+ community levels have been uploaded, and more are being made daily.

  • Story Mode Demo: Currently, the game features a short 5+ story levels as a demo for the upcoming complete story mode. 

UPCOMING FEATURES

  • Complete Story Mode: Over 20+ hand-crafted heart-pounding levels interwoven with an engaging story.

How much does it cost right now?

Project Arrhythmia for PC starts at €2.30 at Eneba, a Steam key, which is 85% under the €15.49 it costs on the official store.

That €2.30 already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 6 offers from 6 stores — and thin supply keeps prices steady rather than falling.

Can you activate it in your region?

All 6 offers are Global, so the code redeems on any account no matter where it was created.

Why is one listing so expensive?

One listing is worth ignoring: the Steam key that Steam has at €15.49 is more than 6 times the cheapest offer and is not what this game costs. The number to work from is €2.30 at Eneba.

So what should you buy?

At €2.30, Eneba is where this one settles.

Most common FAQs when buying Project Arrhythmia for PC in digital format:

It is a key that will allow you to download the game Project Arrhythmia on your PC from official download platforms.
As of 29/07/2026, in United States, the best price we have found in our selection of online stores that include the key for Project Arrhythmia on PC is €2.30.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Project Arrhythmia to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Project Arrhythmia, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.

An absurd, music driven bullet hell, with neon colors and pulse-based rhythms to a chaotic experience, with co-op mayhem always possible. With procedurally timed obstacles and a fully fledged level editor with workshop support, it's a creative fever dream.
