ETA: I confirmed these are definitely from the game and retitled the post. I dunno where “Part 2” is since they’re labeled as Part 1 and 3, however the first video is very interesting and shows our WALL-E doing his job during a time when the other WALL-E’s were still working, amongst other altered and additional movie scenes. Since I figured out for sure that these are from the game, feel free to move or merge, since I’m sure they belong elsewhere now that that’s confirmed.
Nice find, MidgardDragon. Those clips explore a few ideas that must’ve happened at some point, such as WALL-E meeting Hal for the first time- how sweet!- and seeing our WALL-E work amongst the other WALL-Es.
Shame about the graphics. 
Dam i just went to watch them and they have been removed by a third party.
I hate when that happens.
