Curious Expedition is a roguelike expedition simulation set in the late 19th century. Players manage resources and equip expeditions to explore procedurally generated worlds, interacting with native civilizations and looting ruins for treasures while avoiding traps and creatures. The game includes a free Multiplayer Mode and the "The Arctic Expanse" DLC, which adds new arctic biomes, characters, items, and events.
The simulation challenges players to balance resource management for survival with the acquisition of valuable artifacts. Each playthrough presents unique procedural stories and distinct world challenges, encouraging strategic planning and preparation for unforeseen events, including combat against wildlife and mystical creatures. The title also supports Steam Workshop mods, allowing for extensive customization and expanded possibilities beyond the base game.
