Originally an arcade only game, Chaos Code was released as a downloadable game on Asian PSN on December 19, 2012. While it was an arcade exclusive, Chaos Code had updates v1.01 and v1.02 which added balance changes and new characters Celia II KAI, and MG Hikaru to the game. The boss character Kudlak-SIN has also been rebalanced for regular gameplay in the console version. At this time, there is no netplay for the game, but FK Digital has made a post on their blog, stating that they will do their best to patch it in.
"Early civilization of mankind has finally reached the height of its prosperity. The advancement of the universe finally begins! The ongoing development of energy involving many scientists has finally come to a close thanks to one person. This new energy can not be exhausted while maintaining it's power indefinitely.
The energy has been named Chaotics. Heterogeneous energy was being used at the time. Within 10 years, it has taken it's place in the universe as the main energy source of all mankind.
It eliminates the problem of energy shortage, which has been a concern to the universe. I was blissfully unaware at the time that this new energy would rapidly advance all of civilization to the point of an evolutionary halt. It seemed as if...we have stumbled into our own demise.
However, at it's point of discovery, it was no longer an exaggeration to say that Chaotics will be the future power source of all the world. As the developer of Chaotics, I went into hiding and wrote the words of the mystery called Chaos Code. The Earth Union government, which was desperately trying to hide the disappearance of scientists to further understand the power of Chaotics has successfully managed to become a superpower through media propaganda.
The creation of Chaos Code somehow became know to the government and to the public. I announced that there's a huge prize for whoever finds it.
What exactly is Chaos Code? There are other groups and organizations who try to outwit the government, but the government always tries to get ahead using any means necessary. Those who seek power believe that you will be able to dominate the Chaotics if you obtain it. Some believe it will grant wishes, others have their own reasons to find it.
Within the blink of an eye... a competition for Chaos Code has begun."
