Our take: Best for solo players and couples who want a campaign. Also good if you own Expedition Leaders and want more leaders and tracks.
What it adds: A six-chapter campaign for solo or two players working together. Also two leaders, a new research track, and new cards and guardians for normal games.
What it fixes: Adds a story campaign and a proper two-player co-op way to play.
What you need first: Lost Ruins of Arnak (base game)
