Claude Opus 5.5 drew every frame of my app's promo video in code.

No video model. No image model. No animation app.
Even the music and all 26 sound effects are synthesized from scratch.

First cut: one prompt, ~40 minutes.

Claude Opus 5.5 just built this Fortnite Tower Defense map from zero in UEFN.

Winding enemy path, spawn portal, build pads, a wave system, mission gold and house health. All of it.

I connected it to Unreal Engine through MCP and let it work. I barely touched anything.

Fortnite creators are not ready for what's coming.

Sprite Catch just turned 2 months old 👻

Since July 22: • 102K+ collectors joined • 9.4M Sprites caught • 81K+ trades completed • collectors in 167 countries

Thank you all. Here's what 2 months of Sprite catching looks like 🧵

[Mateo Khalil @mateodsk]

Thursdays hit different ⚡

When new Sprites drop, catches jump almost 3× overnight. Every single week.

See you tomorrow 👀
