Unlockable stage

Notice - Waiting Room — Waiting Room's unlock notice.

An unlockable stage is a stage in the Super Smash Flash series that is not available at the start of the game (unlike a starter stage), but must be unlocked. Like an unlockable character, it is required to accomplish a particular in-game feat and once completed, a notice will be shown, telling the player that the stage has been unlocked.
