Buy Cossacks 3 Steam Key

Q: Why is the Steam Key of Cossacks 3 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 Cossacks 3 to your game library. The account format requires more complicated steps and is more prone to errors during activation.

About Cossacks 3

HISTORICAL BATTLES

The Standard edition includes five singleplayer campaigns, which are based on the historical events of the 17th and 18th centuries. Liberate Turin from the French garrison, overcome Ottomans in the Battle of Khotyn, defeat English rebels in the Battle of Edgehill, defend Mogilev against Polish troops, and establish your superiority at la Manche! Prove your strategic skills in battles that determined the course of history.

GRAND SCALE

Become the commander of a colossal force, leading your troops into mass fights with up to 32 000 units present on the battlefield at the same time. 20 unique nations, 100 research opportunities, over 220 different historic buildings, and 120 unit types are at your command. Besides the epic battles on land, you are welcome to build the greatest armada the world has seen and dominate your enemies at sea.

CLASSIC GAMEPLAY

Send your peasants down the mines, chop forests for wood, and don’t forget to manage the crops. Keep an eye on your town's prosperity and the field victories simultaneously, as if you are the true eminent hetman! Dive into the Golden Age of the RTS genre and explore infinite tactical options, including buildings construction and resource production, a broad selection of various units, and the landscape influence.

STRATEGIC CHALLENGE

Once the singleplayer campaigns are completed, advance to conquer the title of the Greatest General in the multiplayer! Up to 8 commanders can compete for the victory or forge alliances against an AI opponent. Do you have what it takes to outsmart the adversaries?

How much does Cossacks 3 for PC cost right now?

Cossacks 3 for PC starts at €3.37 at K4G, a Steam key, which is 50% under the €6.79 it costs on the official store.

That €3.37 already includes the GCDK14DEAL coupon, so apply it at checkout or the store will show you a higher price.

With 40 offers across 17 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.

That puts it 14% under its average of €3.94 since 2017, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Cossacks 3 now or waiting?

That €3.37 key is at one of its best prices.

Those €3.37 are 24% below what it usually costs, measured on the store price.
17 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
Not counting today, only 424 days out of the 2,754 days on record were this cheap or cheaper; the lowest it has ever cost is €1.56.

At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 4,572 daily records of the Steam Key for Cossacks 3 across 30 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 Cossacks 3 format should you buy?

By format: Steam Key from €3.37 and GOG Key from €9.68.

Which Cossacks 3 editions are on sale?

Beyond the standard edition at €3.37, there is the Complete at €4.49 at Driffle, €1.12 more and the Deluxe at €9.93 at Gamivo, €6.56 more. Check on the store what each one adds before paying the difference.

Can you activate Cossacks 3 in US?

29 of the 40 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Cossacks 3 offer?

One listing is worth ignoring: the Steam key that GamesPlanet has at €39.95 is more than 11 times the cheapest offer and is not what this game costs. The number to work from is €3.37 at K4G.
