Classic Mode (Super Smash Bros. Brawl)

Classic Mode is a single-player mode in Super Smash Bros. Brawl that encompasses characters fighting through 12 "stages," or levels, with a set amount of stock. The mode can be attempted on 5 difficulties: Easy, Normal, Hard, Very Hard, and Intense, and provides a trophy of the selected character upon completion, along with coins earned per every completed stage. Additionally, various awards can be given based on completed challenges which pertain to Classic Mode (see below).

As opposed to Melee's randomization in characters in its, each of the stages of Brawl's Classic Mode is based on at least one predetermined universe, where characters and stages that belong to any of the universes are chosen at random. Additionally, the majority of battle types are no longer in a predetermined order (Target Smash!!, Free-for-all, and Final are the exceptions), as the stages may vary in battle types from time to time, thus randomly altering the battle types' order but no two types will appear consecutively.

The enemies on any given stage barring 11 and 12 will all be specified by a set of parameters that varies per stage, such as being metal or giant. There are two Target Smash! levels thrown into the mix of stages. The mode ends with a fight against Master Hand; Crazy Hand will fight as well if Classic mode is played on Hard or higher and the player arrives at Master Hand in less than 9 minutes.

Trivia

 * In Brawl, Halberd will always be fought on in stage 5 due to only Kirby characters being fought in stage 5, and Halberd is the only eligible stage from the Kirby universe for Classic Mode (Green Greens is a Melee stage, and thus never appears).
 * Brawl's Classic Mode is the only one (including the 1P game from Super Smash Bros.) in which Battlefield is never fought on.
