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.


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.


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.


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 deadly attacks across the United States, France, India, Japan, and England 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!


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


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.


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.

Greetings operators,

It is time. Set to be released on April 3, at 6pm, GMT+1, let’s deep dive in a quick preview of what Black One Blood Brothers 1.49 update has in store for you.

Mall of Eden & The Mines
First and foremost, the highly anticipated two new maps: Mall of Eden and the Mines. Both of them will unlock new endless possibilities of gameplay to enjoy.

First, the Mall of Eden is a maze of corridors, shops and rooms, that will allow exciting close combat fights. But beware operators. There is little to no place for mistakes, especially if you have to free hostages or captured agents. Mind the cameras, be stealthy, and plan carefully your next moves.

If you’re more into open theatres, you will enjoy the Mines. With a strong verticality and natural covers, you’ll have to be smarter than your enemies to take advantage of the topography of the map. It’s easy to lose yourself on the bridge and get caught off by the beauty of nature, but you’ll be completely vulnerable on this part of the map. So hurry up, keep your feet off the edges, and focus on your objectives.

Photo & Video Mode
1.49 is also bringing a fan favorite feature: the photo and video mode. Create great memories of your missions and custom maps, be creative, and take your game to the next level. Whether you’re a content creator or just a cinematographic lover, the photo and video feature will unlock a new horizon to the game. It’s easy to customize every aspect of the picture quality to create the perfect video or photo. Don’t forget to share them with us.

And much more...
Speaking of creativity, tons of new assets are brought to the map editor, from new doors to new environment items. It has never been a better time to bring life to your ideas.

These are not the only new features that you’ll enjoy in the 1.49 update: for instance, a new system of waves is being introduced in the siege and war modes. You’ll also notice some UI and quality of life improvements, such as better menus and way to hold your weapons more realistically, and a brand new soundtrack, for a darker game.

Please remove or hide your obsolete clog of Arma 3 scenarios instead of using them as an advertisement for your "game", it's a **** move and it paints you in a bad light.
