LOOKIT THEM SWORDS.
Ah, those were "Demonic Broadswords" I was talking about. This is most likely the shape of Force Edge/Sparda. I'm glad to see that NT is making an effort when it comes to attention to detail (both gameplay and story-wise) in this game.
Unlike Capcom...
(I'm referring to the fact that the story of DMC3 was only awkwardly worked into the first game... and that Nelo Angelo's swords didn't have the shape Force Edge... just the shape of some generic swords... I guess he stopped wanting Force Edge after becoming Corrupted Vergil)
