Pre-release and unused content

Pre-release and unused content are components of a video game that, for whatever reason, are removed or altered before that game is released. Known info about pre-release elements usually comes from one of two sources. The first is information released about a game by its creators before the game is complete. The second is data found within the data of a game that serves no purpose but could have been implemented into the game at one point.

Pre-release and unused content definitions:
 * Prototype (version) / early version / Pre(-)release (version) = A non-final version of a game or part of a game. Pre(-)release (version) is sometimes used to specifically mean an early version that is seen in pre-release materials. The writer should be make clear what is meant.
 * Pre(-)release material = Screenshots, videos, interviews etc depicting or describing a prototype version of the game, or the games development history.
 * Unused = Content that is in the game data, but not used.
 * Cut/scrapped = Content that was in a prototype version, but is no longer. Or content that was planned to be, or suggested to be in the game, but was never implemented. The writer should be make clear what is meant.
 * Beta = not to be used unless it a version is actually a beta version. Should not be capitalised (unless as part of names that are capitalised or at the beginning of the sentence, of course).

Pre-release elements should not be confused with vaporware, entire games which never see release.
