Fallout: New Vegas is an action FPS/RPG developed by Obsidian Entertainment and published by Bethesda for the Xbox 360, PlayStation 3, and PC. Before the game was released changes were made to the game near the end of development. Most of what is documented below can be found in promotional screenshots, videos, and developer diaries.
During initial development, Fallout 3 super mutants appeared in the game as placeholders. Possibly until the New Vegas super mutant variant was created. For example; Neil – a friendly super mutant you meet at Black Mountain – originally appeared as a Fallout 3 super mutant in the beta. You can compare what Neil looked like in the beta to what he looks like in the final below this paragraph.

Another character that was changed in New Vegas is Mr. House. Mr. House uses a master computer to communicate to the player in the Lucky 38 casino. At the time, Mr. House appeared different on the computer screen in the video: developer diary #4 – factions.

The final character that was changed in New Vegas is Sunny Smiles. Sunny wears the same armor in the final like she does in the beta, however her appearance in the game changed somewhat.
The initial build that was showcased at E3 2010 shows the New Vegas Strip without any gates and barriers with significantly more NPC’s. In the final, the Vegas strip was divided into three sections by gates and barriers with significantly less NPC’s. You can see the E3 2010 stage demo of the New Vegas strip below this paragraph.
That’s all the known changes and differences made to the game. There could be more added to this article in the future, but for now, this is all that can be found.

The disintegrator: The disintegrator uses the same model as the laser rifle. The weapon has a damage of 1000 per shot. Because of the damage the weapon can cause with one shot, it was cut from the game, and has been classified as a test weapon. This weapon can only be obtained on the PC port using command codes.
