Donald Mustard, Worldwide Creator at Epic Games, said: "The reason we called this season Nexus War is that this is just the start of lots of stuff we have planned for many years of Marvel integration. This is not the end, this is the beginning. We thought a really good POV-style character which could set this up earlier this year was 'Deadpool', kind of fourth-wall breaking. And Cap in July, building up to this.
"What if instead of treating Fortnite's story like a normal narrative, I'm going to create a world where the island is the main character - so I'm going to treat the island like that traditional arc. And we've planned it that way. Like, I have the story and the narrative structure planned out for many, many, many years."
