Which digital format of Project Arrhythmia should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

If I buy the account format of Project Arrhythmia, will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Can I return a digital game for PC?

Some digital formats allow returns under certain conditions.

The store does not send my order and does not respond to support. What can I do?

Don't worry, we have the solution. We will handle it ourselves.

The final price is higher than indicated.

Many stores add payment fees, taxes,... in the cart. So be prepared to spend a little more.

I'm desperate: They don't send me the game, the store ignores me. I think I've lost my money.

Calm down, don't panic. Contact us and we will help you resolve it as soon as possible.

Q: Why is the Steam Key of Project Arrhythmia safer than the account format?

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.

How much does Project Arrhythmia for PC cost right now?

Project Arrhythmia for PC starts at €2.02 at Difmark Digital Keys, a Steam key, which is 87% under the €15.49 it costs on the official store.

That €2.02 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 8 offers from 8 stores — and thin supply keeps prices steady rather than falling.

Is it worth buying the Steam Key for Project Arrhythmia now or waiting?

That €2.02 key is expensive for what it usually costs.

Those €2.02 are 27% above what it usually costs, measured on the store price.
8 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
Across the 404 days we have tracked it, it has only been pricier than today on 44 days. The lowest it has ever cost is €1.07.

If you do not need it today, waiting pays off: we have seen it at €1.07 and right now you would pay €1.33 more. We will tell you the day it drops.

Worked out from 1,251 daily records of the Steam Key for Project Arrhythmia across 9 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate Project Arrhythmia in US?

All 8 offers are Global, so the code redeems on any account no matter where it was created.

Why is there such an expensive Project Arrhythmia offer?

One listing is worth ignoring: the Steam key that Steam has at €15.49 is more than 7 times the cheapest offer and is not what this game costs. The number to work from is €2.02 at Difmark Digital Keys.
