The Brand Island Index
Most brand activations in Fortnite are dead by day two. The data is public. We're the only ones reading it.
Super Motion Collective runs the Brand Island Index — current and historic audience data on the brand and IP islands in Fortnite worth watching. We use it to publish what works, advise brands before they build, and build maps people actually come back to.

The no-budget creator map that sets the bar.
Every number verifiable in public Fortnite play data.
The problem
Beautiful worlds, empty by week two.
Brands keep buying Fortnite activations like TV spots: a build, a launch, a press cycle, silence. The platform works like software: its algorithm distributes islands that retain players and buries ones that don't. The result is predictable — we watch it daily in the Index — beautiful worlds, empty by week two.
The teams that win operate by the platform's rules: retention-first design, content calendars, creator-friendly moments. The difference isn't budget. Coachella's relaunch peaked 17× below its original. Star Wars peaked on day nine, not day one. The data says the playbook matters more than the spend.

The Activation Blueprint
A 2–3 week sprint before you commit build budget:
- Concept + retention-loop design
- Benchmark targets from the Index (day-2, dwell, favorites)
- Genre and creator-moment strategy
- Vendor-agnostic build spec + realistic budget bands
- Builder due diligence on request
The guarantee: if you proceed to a build with us, the Blueprint fee is credited in full. If you take it elsewhere, you've still got the plan.

Design-led UEFN development
Full activation builds with the retention layer designed first, plus the live-ops retainer: scheduled content drops timed to your brand calendar, sold as what they are — owned media that re-activates your audience. We've measured a single update recalling 24× a dormant audience.
The accountability line: your island's day-2 retention gets benchmarked against the category median in public data. Miss it, and your first content update is on us.
Why us
We see the whole board, and we build on it.
We see the whole board.
The Brand Island Index follows the brand and IP islands worth watching — current and historic launch curves, retention, builder attribution. Nobody pitches you from better data, because the data is the same data we publish.
We're builders, not just analysts.
Super Motion ships its own UEFN games — the same retention discipline we sell is the one we live on.
Everything we claim is checkable.
Our teardowns run on public data. So will your results. We think that honesty is the point of the medium.
