A clear FAQ on what The Missing Expedition adds to Lost Ruins of Arnak, how the campaign works, and what you need before buying.
Quick answer
The Missing Expedition is an expansion for Lost Ruins of Arnak that adds two new leaders, two new research tracks, and new artifacts, items, and assistants. It can be added directly to your base game or played as a solo or two-player cooperative campaign.
What the expansion adds to your games
The Missing Expedition is built around two new leaders, each offering a different strategic angle, and two new research tracks that open alternative paths to knowledge. It also expands your expedition team with new artifacts, items, and assistants, so the mix of cards and options you manage during a game grows.
Campaign versus standard play
You can treat The Missing Expedition as a straightforward addition to your Lost Ruins of Arnak base game, mixing its new leaders, tracks, and cards into regular play. Alternatively, it can be discovered as part of a solo or two-player cooperative campaign, which gives the expansion a structured, progressive way to play through its content.
What you need before buying
This is an expansion, not a standalone game. It requires Lost Ruins of Arnak to play, so if you do not already own the base game, plan for both. The product listing does not specify a player count or play time for the expansion on its own, so check the base game’s details for those limits.
