What it had to solve
A battle royale has no story by default. Mustard — who ran Chair Entertainment through Shadow Complex and Infinity Blade before becoming Epic's worldwide creative director in 2016 — built Fortnite's storytelling experiment on top of a genre defined by matches, not plot.
The idea
Treat the game world itself as the story: a continuing arc of cracks in the sky, kaiju and a black hole, with rifts pulling Marvel and Star Wars into one universe.
How it works
Fortnite's seasons advanced one world-breaking narrative: cracks in the sky, giant kaiju battles, a black hole. Reality-bending rifts let Marvel, Stranger Things, Dragon Ball, Star Wars, Naruto and Futurama characters coexist in the same universe, with Mustard as the public face of the experiment.
What it did
The Verge's verdict on the result: 'There's nothing else like it' — the world's foremost battle royale carried a literal world-breaking narrative. Mustard retired in September 2023 saying Fortnite's teams are 'in the best hands'.
Background
Donald Mustard ran a successful studio that showed what the Xbox and iPhone were capable of before he became the face of what The Verge calls one of the biggest and boldest storytelling experiments in history. His studio Chair Entertainment — founded by members of the Advent Rising team — broke Xbox Live Arcade's sales records with Shadow Complex in 2009, selling 200,000 copies in a week, then turned Epic's Epic Citadel tech demo into Infinity Blade, Apple's go-to demo for the iPhone's graphical chops for years, despite originally being conceived as a Microsoft Kinect title.
In 2016 Mustard became worldwide creative director at Epic Games, and then came Fortnite. Originally a very different game, it was moulded by PUBG's success into the world's foremost battle royale title — and then into a game with a literal world-breaking narrative: cracks in the sky, giant kaiju battles, a black hole, and reality-bending rifts that allowed Marvel, Stranger Things, Dragon Ball, Star Wars, Naruto and Futurama characters to all coexist in the same universe.
On 8 September 2023 Mustard announced he was retiring that month. 'I'm excited to spend time with my wife and family and am forever grateful for @TimSweeneyEpic and the Epic Games family,' he wrote. In his goodbye note he said Fortnite's teams are 'in the best hands' and still working on 'huge, jaw dropping, amazing things'. The Verge's epitaph for the experiment he led: 'There's nothing else like it.'
Why it lands
The narrative lives in the shared world rather than cutscenes, so every player experiences the same story beat at the same time.
The rift device made crossover IP diegetic: Marvel or Star Wars characters arrive through the world's own cracks instead of a licence announcement.
One-off world events (the rocket era's descendants: kaiju, the black hole) turned the map itself into an evolving protagonist.
A genre with no story — battle royale — became the industry's most-watched narrative platform.
What you can take
A live game can carry a decade-long story if the world itself changes: one-off events leave permanent marks, and borrowed universes keep the map surprising without new infrastructure.
Since then
Mustard's September 2023 retirement closed the tenure that spanned Shadow Complex, Infinity Blade, Battle Breakers, Epic's first full-length VR game Robo Recall, and Fortnite's metaverse era. He said the teams remain at work on 'huge, jaw dropping, amazing things' to come.
