Smash Bros. director, Masahiro Sakurai, has revealed the latest stage for the 3DS version of Super Smash Bros., from the 3DS game, Tomodachi Life.
Sakurai unveiled the new stage on Miiverse and explained how the front walls of the apartments disappear when a fighter moves into it. The rooms themselves are randomly selected from a number of different types. The game will also use the data from your 3DS to populate the stage with your Mii characters.
Super Smash Bros. for 3DS is due to be released on October 3. The Wii U version, meanwhile, is due to be released some time in winter 2014.
