Carnage Heart

By 2073, war has evolved. The battle for domination is now a game fought on the moons of Jupiter by warrior mechs armed with deadly firepower. You control an army of cyber gladiators. More importantly, you design them, deal for parts, set up assembly lines and devise battle plans. When the game begins, whoever has created the most diabolical strategies and deadliest mechs wins!

Carnage Heart is a video game for the PlayStation, developed by Artdink. Its gameplay is a mecha-based, turn-based strategy game, where the player takes the role of a commander in a war fought by robots. The robots, called Overkill Engines (OKEs), cannot be directly controlled in battle; they must be programmed beforehand to behave in a certain way under certain conditions using a flow diagram system.
