Hellfest reveals its 2026 lineup and announces the release of ARTE Riff Mountain!
Hellfest announced the release date of ARTE Riff Mountain, coming on November 21st, 2025, and revealed its official cinematic trailer.
A few months ago, we were invited by EPIC GAMES to come and present at the Unreal Fest our concrete approach to creating interactive phygital experiences.
Since 2010, SoWhen? has been dedicated to establishing meaningful connections between brands and their audiences in various retail environments, event venues, showrooms, and public spaces through its creation of virtual and phygital experiences.
By leveraging the flexibility of the Unreal Engine and our own developments, we have unlocked the potential to offer virtual worlds with alternative forms of control and interaction, moving beyond traditional touchscreens and buttons.
In this session, we dive into the world of phygital and immersive experiences, allowing the audience to interact with virtual universes through gestures and connected physical objects, and even through fun interactions with virtual characters.
As the boundaries between the physical and digital worlds continue to blur, the enchantment of this fusion intensifies.
We are excited to present concrete examples from our clients that demonstrate the transformative power of these innovative approaches.

We invite you to join us this year at Unreal Fest, which will take place in various countries!
