If there was a roblox movie, it wouldn't be about saving the universe, I depict it as similar to A Minecraft Movie.
The characters stumble across an orb resembling the spawn orb, it engulfs their environment and then spawns them inside a baseplate that quickly turns into a mix of all the classic Brickbattle games. also with classic maps (Crossroads, Roblox HQ, Doomspire, etc.)
Weapons rain from the sky, landing in all of the people's hands as the other team spawns.
I saw no use in Noob, Builderman, or Bacon appearing, I liked the idea of Guest appearing.
Because if I did,
"I... am Noob."
Some other stuff happens, and here's what I like to think.
[talking about stuff]
CHARACTER1: "Hey! That guy over there can help us!" (referring to guest.)
[they walk to guest
CHARACTER2: "Sir? can you help us? we're trying to get home here and war doesn't seem like the best option here."
[Guest doesn't respond]
"Hello?"
"can you hear us?"
