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! 
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. 
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. 
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.
