Not much is known about the Worms game except that it's a new entry in the storied franchise. Nutjitsu, on the other hand, is already available on the Windows Phone store. It involves sneaking around various levels in attempt to steal back your clan's sacred acorns from the kitsune samurai and their horde of villainous foxes.
ID@Xbox, short for Independent Developers @ Xbox, is a relatively new program established by Microsoft to "offer game developers the same great benefits that existing Xbox developers have today, including the full power of the console, cloud services, Kinect and the Xbox Live toolset such as Xbox SmartGlass, multiplayer, Achievements, Gamerscore and more." It's designed to cater more towards indie developers in an attempt to provide equal opportunity as some of the larger Xbox publishers.
