The year is 2073, and the moons of Jupiter have become the new theater of war. Human armies are obsolete — what matters now is the design of your mechs. As a commander in this arms race of steel and strategy, you engineer your cyber gladiators from the ground up: sourcing components, running assembly lines, programming combat logic, and devising the battle plans that will either dominate or destroy you. Carnage Heart rewards the tactician who out-thinks the enemy before the first shot is ever fired.
