JRPG-Inspired Auto-Battler, Duelist: Idle Expedition, Out Now

Hong Kong, China - October 8th, 2026 - One Interactive Studio and Infini Fun are celebrating today’s release of Duelist: Idle Expedition on Steam with a new launch trailer. Duelist: Idle Expedition is an idle auto-battler designed to live on your taskbar. Build and manage a travelling Guild of hand-drawn Duelists, watching them fight, grow, and adventure across the Continent.

Duelist: Idle Expedition is available now for $8.99 USD / €9.19 EUR / £7.99 GBP, with a 20% launch discount for the first two weeks. Two DLCs launch alongside it: the Supporter Pack ($1.99 USD / €2.09 EUR / £1.79 GBP, also 20% off at launch) adds Camp Four Seasons skins, and the Beginner Pack ($0.99 USD / €1.09 EUR / £0.95 GBP) adds a new character, the Instructor, plus a resource pack. The Beginner Pack is free for the first month.

There are 91 unique roles spanning 7 main classes and 21 sub-classes for you to recruit. Defeating regional Duelists to win the alliance of their followers will unlock unique regional combat styles that allow you to further refine your team’s strategy. Equip them from among the 200 pieces of equipment there are to grind for, customise that equipment through enchantment and support your team with essential resources while travelling the continent.

To thank players for their support, One Interactive Studio is giving away an idle reward package during the two-week launch discount. It includes the Oathsword, a Mythic weapon whose basic attacks deal percentage-based True Damage, along with two late-game "Joke Gears" to add some extra fun to every expedition. The Golden Poop falls from the sky and slows enemies who step on it by 90% for 2 seconds (low physical damage, maximum emotional damage), while the Mighty Weight makes your Duelist 10% bigger and 10% slower every 3 seconds in battle, because bigger is better, and bigger is justice.

The game offers a deep camp management system complete with a Tavern to find new recruits, a Blacksmith to provide your squad with superior equipment and a shopkeeper who can sell your spoils to secure the funds needed for supplies.
