Duelist: Idle Expedition Demo Launches on Steam Today

A pixel-art idle RPG demo arrives ahead of the full Q2 2026 launch

Duelist: Idle Expedition has launched its Steam demo today, May 8, 2026, giving players an early look at One Interactive Studio’s pixel-art idle RPG before the full release.

Published by Infini Fun, the game blends JRPG-inspired party-building with idle progression, allowing players to assemble a squad, send them into automatic battles, gather loot, and manage a growing camp in the background.

The full version is planned for Q2 2026 and is set to include more than 90 JRPG-inspired roles, including 7 main classes, 21 sub-classes, and 91 specialised roles. The Steam demo focuses on the early game systems, including party setup, loot, enchantments, and camp facilities.
