That means that regardless of whether a fighter is facing left or right, their arms and legs will look the way they should in terms of the foreground and background. This is a new development in the Super Smash Bros. franchise.
"Mario, for example, will have his chest shown in the foreground regardless of whether he's facing right or left," said Sakurai, who showed off the detail with the screenshot above, which features Mario and Greninja, a Pokémon. "This was quite a tedious task, but thanks to it we can show the best features of each character even better."
It's unclear if this also applies to Super Smash Bros for Nintendo 3DS. Sakurai also posted a second screenshot, this one with Kirby and Bowser. He pointed out that in previous Super Smash Bros. games, you would see the back of Kirby's head if he were facing to the left.
"Now Kirby looks great from any angle," said Sakurai.
Nintendo announced last month that the 3DS version of the new Super Smash Bros. game will be available this summer, while the Wii U version won't be released until this winter.
