Which digital format of Subject 13 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 Subject 13 , 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 Subject 13 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 Subject 13 to your game library. The account format requires more complicated steps and is more prone to errors during activation.

How much does Subject 13 for PC cost right now?

Subject 13 for PC starts at €0.31 at HRKGame, a Steam key, which is 97% under the €9.99 it costs on the official store.

That €0.31 already includes the Gocdkeys12 coupon, so apply it at checkout or the store will show you a higher price.

10 stores carry it, 10 offers in total and 9 available right now; the figure above is the cheapest of the ones you can actually order.

That puts it 39% under its average of €0.51 since 2017, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Subject 13 now or waiting?

That €1.09 key has never had a real discount yet.

The Steam Key has been on sale for 111 months and its biggest drop has been 6%.
Only 4 stores sell the Steam Key, and with that little competition the price barely moves.
Not counting today, the Steam Key was at this price or lower on 103 days out of the 317 days on record: this is basically what it always costs.

If you are in no rush, it is worth waiting for a sale. We have seen it at €1.04 and we will tell you the day it drops.

Worked out from 644 daily records of the Steam Key for Subject 13 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 Subject 13 in US?

9 of the 10 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Subject 13 offer?

One listing is worth ignoring: the Steam key that Steam has at €9.99 is more than 32 times the cheapest offer and is not what this game costs. The number to work from is €0.31 at HRKGame.
