Product Description

Professor Kutil has vanished while exploring the lost ruins of Arnak. Now your expedition must follow the clues, retrace his steps, and discover what happened deep within the island.

The Missing Expedition adds a story-driven six-chapter campaign for solo play or two-player cooperative play, giving Arnak fans a new way to experience the adventure. Each chapter offers its own challenge, while the added cards, sites, artifacts, guardians, assistants, and research tracks bring more variety to standard games as well.

This is more than a campaign box. It also expands the main game with two new expedition leaders, fresh strategies, and extra components that can be mixed into regular Lost Ruins of Arnak games for 1 to 4 players.

Care & Maintenance

Store all cards, tiles, boards, tokens, and campaign components neatly in the box after play. Keep the game away from moisture, direct sunlight, and rough handling. Because this expansion includes many cards and campaign pieces, sorting components after each session will make future setup much easier. Card sleeves can help protect frequently used cards, especially if you plan to play the full campaign.
