The project

The project

I moved to London to join PlayStation London Studio as it built something new: a co-op PvE combat game set in a fantastical reimagining of London. I founded the UX department, bringing UX principles and player-centric design to a studio that hadn’t had them before.

In February 2024, London Studio was closed in the PlayStation-wide layoffs after two decades of games — and the project was cancelled with it. That’s the moment this portfolio was last rebuilt. But the story didn’t end there (see 03).

What I did

What I did

Founded the UX department

Established UX practice from scratch and worked across every discipline — especially UI Art and Design — to create fun, accessible experiences.

Implemented in engine

Directly implemented UI and other game systems in Unreal and in the studio’s custom Soho engine — designs delivered as working features, not just mockups.

User research & playtests

Helped run studio-wide playtests — creating surveys and analyzing both quantitative and qualitative data.

Prototyping

Built prototypes in Adobe XD and Figma to quickly test and iterate on game ideas.

Documentation

Created and maintained clear design documentation across the project.

Cross-studio collaboration

Created monthly PlayStation Studios UI/UX meetings, connecting practitioners across the whole family of studios.

The game lives on

The game lives on

After the closure, some of my former teammates founded Twisted Works, an independent London studio, and acquired the rights to carry the vision forward. Their debut title, Cast Outs, was revealed in December 2025: a modern-fantasy co-op action game set in a mythically reimagined London, where spellcasting “hits with the physical impact of a brawler and the immediate kick of a shooter.”

It’s planned for PS5, Xbox Series, and PC, with an early-access beta targeted for early 2027. Seeing the work our team started find its way to players — that’s the best possible epilogue.
