Carnage Heart is a strategy game for the Sony PlayStation 1, blending elements of simulation and programming. Released in 1995, the game's unique feature is its focus on designing and programming AI-driven mechs, known as Overkill Engines (OKEs), for combat. Players use a flowchart-based programming interface to dictate the actions of their OKEs in battle. With a science fiction storyline, the player must apply tactical skills and programming logic to succeed in various missions, emphasizing strategic planning over direct combat. It caters to fans of both mecha and complex strategy games.
