Nintendo recently shared a new Nintendo Switch My Way – Super Smash Bros. Ultimate Video that gives a glimpse of what fresh things we will see in the game. The video shows a group of young kids exploring and playing together. In the beginning, there is a blurred out screen that shows “Stage Builder” icon – (Thanks Polygon) in the menu.
The image is unclear, still, it is good enough to speculate that Nintendo is adding a new Stage Builder Mode in Super Smash Bros. Ultimate. Similar to Super Smash Bros. Brawl and Super Smash Bros Wii U edition the mode will allow players to bring a custom stage based on their creativity.
The mode is not visible in the current edition of the game, this will be added after an update we assume. The video also reveals new foe Inkling joining the battle, around four players can compete with each other using controllers similar to PS4 controllers, not Joy-Con.
