Classic Mode (SSB4-3DS)
Classic Mode is a single player mode in Super Smash Bros. for Nintendo 3DS that encompasses a series of battles against various characters. Undergoing a huge revamp from previous versions of the mode, the player is now given a choice of a set series of paths to choose from. Rewards such as Equipment and Custom Moves will be given to the player after the mode's completion.
Each path is marked by a series symbol, representing a battle set in a stage from that universe against at least one character from it (with the possibility of more characters from unrelated ones), and a color denoting the battle's difficulty: red indicates a path to more rewards but a harder difficulty, green indicates a medium level of difficulty with moderate rewards, and blue indicates the easiest battle with little reward. The final path to Master Hand is colored blue.
All of 1-on-1, 2-on-2, Metal, Giant, and four man free-for-all battles return, the last taking place on one of the characters' home stage. Unlike previous Classic Modes, returning stages are playable in the mode. Multi-Man battles also return, either against a normal character or a Fighting Mii Team, but this time they always are the last round before Master Hand. Winning a match rewards the player with gold, as well as additional gold, Custom Parts, or Trophies as randomly selected beforehand (in multiples of 0-5).
Instead of selecting an amount of stock to carry throughout an entire run, players always start each stage with 2 stock regardless of difficulty. The difficulty selection was also changed to the Intensity system, very similar to the Fiend's Cauldron in Kid Icarus: Uprising, which allows players to invest gold to either raise or lower the difficulty, and with it the possible rewards. The basic intensity, which requires no gold to access, is 2.0; it can be lowered to 0.0 or raised to 9.0.
In addition to the overall difficulty, the intensity influences the final boss. On an intensity of lower than 3.0, Master Hand is the basic final boss. On an intensity of 3.0 or higher, a second, black path is unlocked which leads to a battle with both Master Hand and Crazy Hand, along with more rewards. If the intensity is 5.1 or higher, the battle with the two hands will begin as usual, but after taking enough damage, Master Hand will rip open to reveal the new boss Master Core, which possesses several forms and whose starting form is more advanced the higher the intensity. If the intensity is 8.0 or higher, the black path is the only final path.
