Sakurai has just revealed yet another exclusive 3DS stage for Smash Bros. The stage will be based off of Tomodachi Life . The stage takes place in a Tomodachi Life apartment building. Normally the stage’s rooms are hidden by the fourth wall, but they are revealed when you enter the room itself. The rooms are randomized and have different items and backgrounds. Most notably, you can throw hazards into these rooms and leave, revealing them when another player enters. This is great for things like bombs and other knock out items, although the roof of the house prevents vertical knockouts.
Most interesting to note is that you will run into Mii characters while fighting on the stage. The Mii’s are taken from your 3DS data, so you’ll get to see yourself and your friends spectating in the background.
