The new Super Smash Bros. will have an “All-Star Mode” where you can challenge every fighter in the game, taking multiple ones on at a time. Director Masahiro Sakurai explained how the mode works over Miiverse.
“This time, you can challenge every fighter in All-Star Mode from the moment you turn on the game!! This is a survival battle with limited recovery items and no option to continue,” Sakurai wrote.
“However, this mode will be incomplete until you’ve unlocked every fighter… Until then, you can only play against characters that are already available. This is a picture of the bottom-screen menu, with a padlock indicating that the mode is still incomplete.”
“In these battles, multiple opponents appear in one stage, and you clear the battle by defeating a number of them,” Sakurai explained.
“The rest area that appears between battles displays the next opponents and the year the characters made their first appearances, and it also holds recovery items and an occasional reward.”
“The characters you fight against appear pretty much in chronological order. Behold, the history of Nintendo games!!”
