Battlefield Stage:
Heaven and Hell (Battlefield)
Heaven and Hell is a stage, where it locates between the Hell and Heavens. The map locates on the Border of it, which it possibly locates on Earth Reality.
Heaven is an afterlife dimension, where good and innocent souls go there.
Hell is an afterlife dimension, where bad souls go there and have sometime eternal punishments.
The Layout of map is same as Battlefield and it has mixed Hell-Heaven aesthetic like floating temples in Heaven and Volcanoes in Hell are in the far Background of the map. Also, the map has Columns placed as decoration on stage.
There are some cameo places like Heaven's Garden, where Adam and Eve eat an apple (They don't appear, but the place is still there).
Also, some Angels and Demons from Pop Culture media are flying in Background like Pit (Kid Icarus by Nintendo) in Heaven or Cacodemon (DOOM by Bethesda) in Hell. They don't do anything except flying in the Background and being harmless.
Also, it borrows some aesthetics from previous Smash Battlefield designs like notably the SSB4 and Ultimate ones due to floating temples in clouds.
The places like Heaven and Hell can switch their places at some point, making the map more unique-looking.
Occasionally, you can see our cartoonish God in Heaven and Cartoonish Satan in Hell and they don't do anything, but they appear as Easter eggs sometimes.
I nominate the variation of Battlefield, because it would look unique and appealing.
Besides that, Heaven and Hell are well-known commonplace in Pop-Culture like in games like DOOM or Kid Icarus for example or other media like Hazbin Hotel.
Also, the Stage could represent Religion (It's not gonna be rude for religious people, but we could need some depictions of religion in game, since concept of those afterlife places are very well known and recognizable since the appearance of it back before AD)
I hope you guys like this idea, since I wanted to do something unique...
(I mean, it could work as FD, but I wanted to do something more unique and interesting)
