If you happened to get Super Smash Bros. last year, both for 3DS and Wii U, you might recall being eligible to get the soundtrack of both games if you register them on Club Nintendo. But if you haven’t registered them yet and you’re still after the soundtrack, you might want to get on that.
Tuesday, January 13 marks the last day that the soundtrack offer is available. You must register both games on Club Nintendo’s website prior to 11:59 pm Pacific Time on Tuesday in order to get the soundtrack. The soundtrack is set to be distributed sometime in March to those who registered both games before the offer’s expiration date. This offer is only available to those in the US and Canada regions.
However, the other major offer, the Mewtwo DLC, does not expire until March 31, 2015 at 11:59 pm, so you still have some time to register your games if you want to duke it out as the psychic Pokemon.
