The centerpiece of Carnage Heart EXA is the design and implementation of giant robots called Overkill Engines (OKE).  By themselves, these robots are unimpressive; only by hardware and software modifications do they become truly terrifying machines.  Players will have a multitude of hardware and software options to add to their OKEs including weapons, fuel tanks, armor thickness, and more. 

Software designed by the players is stored on virtual cards that can be slotted into any OKE.  These commands dictate how a unit performs.  Chips on the software card are laid out in a programming chart, where players must choose which actions within the chip are to be prioritized.  Combine together a variety of chips to create complex instructions for your OKEs to use while on the field of battle!

"We've still got a couple surprises in store for our fans before Carnage Heart's release next month," said Hiro Maekawa, President and CEO at Natsume. "These plans include an exciting website where the developers and players can share their creations and battle prowess."
