Nintendo is offering a special promotion for Super Smash Bros. through Club Nintendo; a limited edition CD soundtrack. To get this Smash Brother’s soundtrack, all you have to do is buy and register both Super Smash Bros. for the WiiU and 3DS on Club Nintendo.
There aren’t many details available for this promotion, but there are some sample songs on the Smash Bros. website. Some of the games represented are Kirby’s Dream Land, Nintendogs, Mega Man, Mario and Luigi: Dream Team, and, of course, Pokemon X & Y.
The 3DS version will be available October 3rd, 2014, but there is no set date for the release of the WiiU version, though it is expected around the Christmas season.
With Nintendo giving more recognition to the Pokemon team in the upcoming Smash Brother’s games, it is highly likely that several Pokemon songs will make the cut at being included on the sound track.
