How Unreal Engine 5 helped Thick As Thieves build its gorgeous magic-punk world. Despite the latest tech, developers often favour stylised aesthetics that stand out. Art director Matt Moore explains how the game’s Edinburgh-inspired city of Kilcairn blends medieval architecture with modern neon lighting and even a touch of magic.

Moore notes that Dishonored influenced Thick As Thieves, though the latter takes creative liberties by setting its story in an alternate 1910s timeline. The game features a mix of old-world magic and technology, including three-wheeled automobiles and airships, all underpinned by dynamic global lighting provided by Unreal Engine 5.

With Kilcairn’s nighttime scenes filled with neon lights and moonlight, the game’s stealth mechanics rely heavily on light management. Each room contains multiple light sources that can be turned on or off, contributing to an immersive experience where every shadow counts.

The Edinburgh connection is clear: a team of artists visited the city to gather references, particularly inspired by its unique baronial architecture and narrow closes. The fictional Kilcairn retains this historical richness but adds a fantastical layer of magic, making it a world that feels both familiar and otherworldly.

Moore’s reflections on how the switch to Unreal Engine 5 impacted lighting design highlight the balance between artistic vision and technical constraints. Nonetheless, the final result is a visually stunning game that pushes the boundaries of what an immersive sim can be.
