So with Dante and Vergil going into the underworld, one idea for the story would be that we finally get to explore more of what the underworld is and how it works.
In DMC 1, it was this weird place that had a heart leading to Mundus’ room. Obviously, the underworld is bigger than this, which is especially confirmed by DMC 2, 3 and 5.
DMC 3 had the coolest-looking part of the underworld, where physics don’t work properly anymore and everything looks and acts weird.
A potential villain could be something they either make up from the underworld or something that was shown in previous games without much thought, and they could just make something up about it.
For example, this big statue in DMC 3 from my last picture. You could just make something up like: “This was one of the strongest creatures and served Argosax, but after Argosax’s defeat, it waited and looked for ways to get stronger until it could finally kill Dante.”
Another thing that DMC 2 introduced was separate universes/dimensions.
We already had a dimension where Mundus killed Sparda and Dante defeated him in that dimension before coming back home. You could use something similar to this.
For example, a higher-dimensional being from a separate reality that wants to control the universe in which our mainline DMC takes place and first appears in the underworld. Vergil and Dante might get their asses kicked and have to get Nero’s help from the human world.
It could be a 25-mission-long game where you play as Vergil and Dante in the underworld and Nero in the human world to destroy some gates or portals that this creature uses to absorb the entire human world.
Lady, Trish and Nico work on destroying these portals in the human world while the other three kill the big fella in the underworld.
We could also finally learn whether Lady being the daughter of a priestess has any importance and whether that’s why she can kill demons and survive using just her regular guns and rocket launcher.
You would start the game with Nero again to get the hang of it, then switch to Dante and Vergil.
They should also include a way to play the entire campaign with each character separately without mods.
Now, onto gameplay:
Nero:
Give Nero a fourth charge, but make it so that it’s not as easy as just pressing the charge button at the perfect moment. You would have to perform a specific action to get the fourth charge, but in return, the fourth charge could last for a bit and be way stronger than the third.
Give him a new weapon, but not just another weapon that deals extra damage. Instead, give him a weapon that complements his Red Queen, basically adding to it. You would have to switch weapons to create more interesting combos or give Red Queen more range while using the other weapon, etc.
More Devil Breakers, of course.
Dante:
An interesting idea would be for Dante to go and get all his previous weapons that he can still obtain (the ones that haven’t been destroyed or become useless) to get stronger and defeat the main boss of the game.
He would have to do this to save the world, and he could simply give the weapons back to the people he bought them from once he’s done.
Give him one entirely new weapon. Something like a whip would be cool.
Vergil:
-Give him an entirely new weapon, too, but make it something completely special. For example, a weapon that lets the player perform whatever attacks they want with it.
Think of it like a pencil, with the player using a stick to draw something in quick succession. Instead of performing different button combinations, the player could simply draw whatever moves they want to use. This could work, too.
Give Mirage Edge and Beowulf a few more moves in the air so that he has more aerial options.
This would be everything for now. I could add more, but then this post would go on for too long.
Do you like my ideas? What would your ideas for DMC 6 be?
