Ultimate Destruction was an incomplete level used for the teaser trailer of Geometry Dash, at which point the game was originally titled Geometry Jump. Elements from the level were later used in Base After Base.
- Ultimate Destruction was never intended to be released as an official level, nor was the soundtrack planned to be used again afterwards. Since Update 1.9, it could be selected for use in user levels.
- Ultimate Destruction previews the yellow pad, the yellow ring, the gravity portal, and the cube and ship forms.
- A notable difference from the post-release version of the game is that while flying the ship, the drop-down ceiling has not yet been implemented, allowing the ship to be flown out of view of the screen.
