Press release:
Hong Kong – September 15, 2026 – One Interactive Studio and Infini Fun today announced that their JRPG-style idle combat game, Duelist: Idle Expedition, is set to launch on Steam on October 8th, 2026.

Designed to live on your taskbar, Duelist: Idle Expedition lets players build and manage a travelling Guild of hand-drawn Duelists, watching them fight, grow, and adventure across the Continent, even when you step away. The game runs on a dual-progression loop: on the front lines, battles rage on nonstop, while behind the lines, camp life is thriving. With 91 unique roles spanning 7 main classes, over 200 pieces of equipment to grind for, and a deep camp management system complete with a Tavern, Blacksmith, and Shopkeeper, the game blends satisfying idle progression with genuine strategic depth.

In Duelist: Idle Expedition players will build their Guild from the ground up: recruit Duelists, discover powerful role combinations, gear them up, and lead them into battle across the Continent, all while growing camp facilities, unlocking followers, and opening up new Combat Styles and progression paths.

“Whether you’re a nostalgic fan of pixel JRPGs, a hardcore min-maxer obsessed with build-crafting, or a busy professional in dire need of a quality secondary-screen game, you’ll find your fun here!” Said CK, Game Producer at One Interactive.

“Head over to Steam and add the game to your Wishlist. We’ll see you on the Duelist Continent on October 8th!”
