About Black One Blood Brothers

Black One Blood Brothers is a tactical military shooter game where strategy and coordination are key. Joining the "Black One" unit, you become part of an elite force comprised of top operators from around the globe. Operating independently of any government, this unit works from the shadows, free from political games and diplomatic constraints. As the leader of this squad, you're tasked with executing complex missions where every decision could mean the difference between life and death.

CAMPAIGN MODE: OPERATION "SERPENT'S WHISPER"

During the adventure offered in the campaign mode through Operation "Serpent's Whisper", the story kicks off in response to the insurgent group "New World," which has launched devastating attacks across the globe within days. Your mission is to neutralize this threat and trace the funding behind these attacks through 20 increasingly challenging missions. Be advised, the loss of an operator is permanent!

GAMEPLAY & REALISM

Developed in collaboration with a former French Special Forces Commando Marine, "Black One Blood Brothers" stands out for its demanding and immersive gameplay. Command a squad of 10 operators, each with unique skills, and seamlessly switch between them to leverage their specialties in either first-person or third-person view. Success hinges on meticulous planning, optimal equipment management, and teamwork.

BATTLE PLANS & QUICK ORDERS

Implement precise action sequences for each squad member using a complex yet intuitive "Battle Plan" system. Organize your forces into multiple teams, coordinate their movements, and devise custom tactics to tackle any situation, or switch to real-time command with "Quick Orders" for dynamic decision-making.

HIGH-RISK MISSIONS

Undertake high-risk missions including target neutralization, hostage rescue, bomb defusal, and retrieval of secret documents.

CUSTOMIZE YOUR SQUAD

Customization is at the heart of "Black One Blood Brothers." Build your squad from the ground up, selecting each member's skills and arming them with the finest arsenal.

REPLAYABILITY & GAME MODES

With a variety of game modes (Dynamic campaign, Spec Ops, War, POW, Siege, Lone Wolf, Blind Ops) and a powerful, user-friendly map editor, "Black One Blood Brothers" offers vast replayability. Customize your missions, adjust difficulty, select your battlefields, and share your creations with the community through the Steam Workshop.

How much does Black One Blood Brothers for PC cost right now?

Black One Blood Brothers for PC starts at €3.88 (€4.28 with fees) at Key4Games, 71% under the €14.99 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €14.99 (no fees) at Steam.

That €3.88 (€4.28 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 11 offers from 9 stores — and thin supply keeps prices steady rather than falling.

Is it worth buying the Steam Key for Black One Blood Brothers now or waiting?

That €14.99 (no fees) key is expensive for what it usually costs.

  • Those €14.99 (no fees) are 161% above what it usually costs, measured on the store price.
  • Only 6 stores sell the Steam Key, and with that little competition the price barely moves.
  • Across the 773 days we have tracked it, it has only been pricier than today on 0 days. The lowest it has ever cost is €1.45.
If you do not need it today, waiting pays off: we have seen it at €1.45 and right now you would pay €13.54 more. We will tell you the day it drops.

Worked out from 1,914 daily records of the Steam Key for Black One Blood Brothers across 8 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.

Are these stores safe to buy Black One Blood Brothers from?

One caveat worth €0.31 (€0.10 with fees): the €3.88 (€4.28 with fees) at Key4Games is the cheapest, but that store carries only 37 Trustpilot reviews, so there is barely any track record behind it. Difmark sells the same shared account for €4.19 (€4.38 with fees) — €0.31 (€0.10 with fees) more — backed by 14.2k reviews and a 4.1 out of 5, which is a small premium for a seller thousands of buyers have already tested.

Which Black One Blood Brothers format should you buy?

With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.

The key at Steam costs €11.11 (€10.71 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.

The 3 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.

Can you activate Black One Blood Brothers in US?

10 of the 11 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Black One Blood Brothers offer?

One listing is worth ignoring: the Steam key that K4G has at €79.35 (€86.49 with fees) is more than 20 times the cheapest offer and is not what this game costs. The number to work from is €14.99 (no fees) at Steam.
