Nintendo is offering a free CD soundtrack to those who buy Super Smash Bros.
There's a catch, of course – gamers must buy both the 3DS and Wii U versions to receive it. Once both games are out users must simply register codes for both games on Club Nintendo.
Neither the track list or an estimated release date have been unveiled, but the fact that it was tweeted on Nintendo's European account does at least mean UK buyers should be eligible.
Super Smash Bros is out on October 3rd on 3DS and by the end of the year on Wii U.
