What is "shadowclan"

ShadowClan is a cancelled video game for the PlayStation 3 and Xbox 360 consoles. It would have been a single-player offline game with an online multiplayer option. The game was to be set in modern-day New York City, where gangs fight for territory. In the single-player game, the player controls a ninja who must use stealth and violence to overcome other gangs, the player is joined by allies who are controlled by artificial intelligence. The online component would have allowed players to create their own ninja clans to battle with rival players.
