Ultimate Destruction

Ultimate Destruction was a demonstration level used for the trailer of Geometry Dash prior to its release, at which point the game was originally titled Geometry Jump. Elements from the level were later used in Base After Base.

Trivia

 * Ultimate Destruction was never intended to be released as an official level, nor was the soundtrack planned to be used again afterwards.
 * Roughly two thirds of the level were used for the trailer.
 * Jump pads, jump rings and gravity portals make a first appearance, in addition to the ship form.
 * A notable difference from the post-release version of the game is that while flying the ship, the drop-down ceiling had not yet been implemented, allowing the ship to be flown out of view of the screen.
 * The cube seen in the preview is normally unlocked by completing Can't Let Go.
 * Despite the soundtrack not being used for an official level, Update 1.9 introduced the ability to select it for custom levels.
