The article states that the game has been in development for well over a year, and will feature modes like Story, Battle Royal, Tournament, Practice, and Winner/Loser Stays. The game will also boast a robust online component that should encompass a few of the aformentioned modes, and maybe some others. No characters were confirmed, but we'll keep Leonardo, Michelangelo, Donatello, and Raphael in the "probably" pile. In any case, you can be assured that we'll keep our eyes on this game. Anything that mixes Smash Bros., Ninja Gaiden, and our heroes in a half shell is okay in our books.
