Is it worth buying the Steam Key for Hearts of Iron IV Battle for the Bosporus now or waiting?

That €3.79 (no fees) key is at its usual price: no bargain, no spike.

  • Those €3.79 (no fees) are 8% above what it usually costs, measured on the store price.
  • 12 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
  • Not counting today, 1,076 days out of the 1,401 days on record were this cheap or cheaper; the lowest it has ever cost is €1.99.
It is not a bad price, but it is not this Steam Key's floor either. If you are in no rush, we will tell you the day it drops.

Worked out from 3,788 daily records of the Steam Key for Hearts of Iron IV Battle for the Bosporus across 20 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.

Which Hearts of Iron IV Battle for the Bosporus format should you buy?

By format: Steam Key from €3.79 (no fees) and Steam Gift from €5.13 (€5.88 with fees).

Can you activate Hearts of Iron IV Battle for the Bosporus in US?

13 of the 21 offers work on US — the Global ones plus the ones issued for your own region.

Do you want to buy Hearts of Iron IV Battle for the Bosporus for PC cheaper than in official stores?

Then from Gocdkeys, we recommend that you go for the digital version of the game. The digital versions of the PC games are available in cd key or digital code format, a quick and easy method to download games from the official download platforms such as Steam, Epic Store, Uplay and Origin, among many others.

What is Hearts of Iron IV Battle for the Bosporus 's cd key?

The cd key, or STEAM Key, is a digital code that will allow us to download the Hearts of Iron IV Battle for the Bosporus  game in our PC from the Steam game platform. A series of numbers and letters that when introduced in our library of games will allow us to download this game in digital form.

How can we find the cheapest price for the Hearts of Iron IV Battle for the Bosporus STEAM key?

That's our job and we do it very well! From Gocdkeys we offer a comparison of prices and stores that sell the digital version, in the form of code, STEAM key or Steam Gift of Hearts of Iron IV Battle for the Bosporus . Simply enter the list and you will see all prices ordered from lowest to highest, so it will be easier to find the best deals and prices in a complete selection of online stores specializing in the sale of digital games.

Each and every one of them has been checked by our team and they offer the best guarantees that the whole process, from the purchase to the delivery of the game keys, is done in the fastest and easiest way possible.

What digital versions of Steam games are available?

Although from Gocdkeys we indicate that this is the cd key, it can also be available in "Steam Gift" format which means that instead of receiving a code or digital key after purchase, we will receive an activation link, which will activate the game directly in our game library. Steam Gifts can be regionally locked, so please pay attention before purchasing this version.

You will see on a label, next to the price, the version or edition that is sold in each of the stores. If none of them appears, it means that it is a standard version of the game and in digital key format.

After that, and always depending on the version of the game you have bought (cd key or Steam Gift) you will have to enter this key in your "Game Library", in "Add product" and in a matter of seconds the download of the game will start.

If it's a Steam Gift version, simply log in to your account and click the activation link that we've sent you in your email.

Battle for the Bosporus is a DLC of the prestigious strategy video game Hearts of Iron IV from Paradox studio. It is set in the First World War and allows the player to control one of the powers involved in the conflict and change history.

In this expansion we counter with an expansion of content for the nations around the Aegean and Black Sea such as Turkey, Greece or Bulgaria. New historical events and happenings have been added to make playing with these nations as attractive as playing with the great powers.
