So,
Put in simple man's terms.
V1 is a machine fueled by blood and was made for counterattacks against a faction in a war called, The Earthmovers. So on and so forth, the war ended, V1 had no purpose and they made another machine named V2, but they went broke after building V1, so they could only build one. (Oh yeah, they also built drones.) Humanity found the door to hell, began extracting materials (🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸) from Hell unnoticed. Until they found out that a worker got taken over by Hell, then they shut the whole thing down so they wouldn't get killed. Then everyone died. No one knows how because no one is alive to figure it out. Then God f**king disappears for no f**king reason, Different rulers of the levels of hell make levels to their own vision since the angels who watched over hell went back to heaven to make a new council over God's absence. Then Gabriel is sent down to f**king murder them and becomes the judge of hell or smth. Then the game starts and so forth. (Minos is taken over by snakes, and a predecessor takes over for King Sisyphus or smth) and that's pretty much it.
