Microsoft has announced official pricing for Kinect in the UK - with the motion-sensing Xbox device getting a standalone SRP of £129.99.
That price ($149 in the US; €149 in mainland Europe) will also include Kinect Adventures - which features 20 mini-games, including raging rapids and ball titles.
A hardware bundle including Kinect, a new 4GB 360 console and Kinect Adventures will set you back £249.99 ($300).
Kinect games, including Kinectimals, Kinect Sports and Kinect Joy Ride, will retail for £39.99 each.
"Kinect for Xbox 360 offers fantastic new ways to be entertained for the whole family," said Chris Lewis, vice president, Interactive Entertainment Business at Microsoft Europe.
"With full body, voice and multiplayer play straight out of the box, Kinect is a unique way for everyone to enjoy controller-free fun and entertainment."
Microsoft promises more than 15 games available at launch - and says the device will ensure 'living rooms will become gyms, nightclubs and sports stadiums with a wide range of innovative and groundbreaking experiences from the world's leading video games publishers'.
