Here is a quick overview:

• Two new challengers
  • Lupinus (voiced by Yukino Azuma) – A steel-armed agent who splendidly dances about the earth and sky.
  • Ray (voiced by Daisuke Yokota) – A heavy attack hitman who makes use of special links.
• New game modes added – In addition to the Arcade Mode, Practice Mode, and Versus Mode from the original game, New Sign of Catastrophe adds a new Survival Mode, Score Attack Mode, and Mission Mode featuring more than 50 unique challenges.
• Unique Battle Style Settings – In addition to the “Run” and “Step” movement styles featured previously, in the home version you can set the performance of the characters in “Chaos” and “Boss.”
• Character Customization Evolved – Chaos Code‘s greatest feature is that you can freely set your character style. If you set an original color in the newly added “Custom Color” setting, you can further make a character all your own.
• Network Support – With network support, you can battle against players all over the country.
