Before the end of the month you should be able to add Wiimote-like motion-sensing to the Xbox 360’s controller called Xilt. It’s a mod that’s said to install in as little as 10 minutes (only seven wires are needed) and was built “from the ground up” to ensure maximum flexibility. Yeah, info… not so much.
Still, it’ll work with both wired and wireless controllers. When it’s releases, golly gee, hopefully they’ll be cool YouTube videos and the like showing kids acting all willy nilly.
