Beta Content, also called BETA Content, are editions of enemies, levels or anything similar which are scrapped, unreleased or otherwise removed from the final edition of a game. Most beta content can only be found through hacking, demonstrations, game files or other unofficial, or unlicensed means. Beta content can also be found in pre-released screenshots or other similar materials, ranging from differing designs and textures to entirely different level designs and aspects.
American McGee's Alice
Tweedledum and Tweedledee
Fortress of Doors
Platforms were constantly rearranged during development and the textures were also changed. Many brick patterns became chess-like patterns and vice versa.
Vale of Tears
The Vale of Tears was more colorful; the sky was blue and there was just less fog and many textures were brighter.
When Alice was running away from the large marble-like boulder in the Vale, it was possible for the camera angle to move position.
In an earlier trailer, during times when Alice can become chess pieces, parts of the ground could fall away making the chess puzzles more difficult. In the final edition, the holes in the ground are preset and all obstacles can be easily avoided.
There were several areas of the Majestic Maze which did not make it to the final edition, including an area with a red smog pit.
The target reticle was originally a red circle which would surround and track the enemy's feet.
Alice originally had an ability similar to Dodging called "Dash."
In the Beta trailer, while Alice is Gigantic she is wearing her Royal Suit dress. In the final game, when upgrading to her giant form, Alice's dress will become Classic again; even if the player has selected the Royal Suit by choice.
Alice's weapons were based upon tarot, and the color of her dress would change depending on which weapon was equipped.
Alice's hair originally had a slight fringe similar to her original design. This was later changed so that her hair would curve around her face.
Alice's hair would also stay the same no matter the domain or area; Wonderland or London.
Large chunks of Alice's dress would cut into her leg, and the apron would cut into her dress. This was later fixed.
Alice's dress symbols were originally the same as her original game design. The reason for the change is unknown.
Alice had more than one voice actress. Some lines were spoken in a more "posh" voice by a different actor, rather than Susie Brann.
The White Rabbit was originally set to guide Alice through the Vale of Tears, and was originally meant to be met at the beginning rather than the Cheshire Cat.
The White Rabbit would have played a more active role in the game, telling Alice what to do, and even telling her to run from the police at one point. His role seemed to have been given to the Cheshire Cat instead, and Rabbit only has a minor appearance in the final version.
Originally, Alice's burning home appeared in the streets of London rather than in Hyde Park.
The London storyline was originally set to be larger, with combat included. Alice would set out to meet Pris Witless at her apartment and, presumably, Alice would hallucinate that Pris was transforming into the Jabberwock and she would either push Pris off the roof, or Alice would simply black out and wake up later with Pris gone. Either way, Alice would be wanted for Pris' murder and must now evade police capture by way of maneuvering atop the rooftops of London. (The objectives can still be found in the games files.)
At one point, Alice would find herself at the scene of Pris' gruesome murder in a house, although it's unknown if she is the murderer or not.
Alice is seen accidentally falling off the roof onto the pavement of a street below, presumably hitting her head. The street is seen crumbling into her way to Wonderland, implying this was how Alice was originally meant to return to Wonderland.
Although unconfirmed to have been developed, the concept art shows Alice originally had to escape Gaol using sneak-like abilities. She also had to throw rats at the police. This could possibly have been part of the police chase scenes.
Alice could sneak through London and she could shift herself slowly across piping attached to the sides of buildings.
Alice could perform actions and animations similar to the ones shown in American McGee's Alice, including her dangling and shifting around ledges and pulling herself up.
