The Vivarium Expansion isn't just an add-on — it's a transformative evolution of Machina Arcana, deepening the horror and strategy in ways never seen before. Each Vivarium scenario weaves its own dark tale. The stories expand beyond the icy mountain, unveiling haunted ruins, forsaken domains, and realms lost in time and space. It incorporates new decks into your game to transform every session with immersive and unpredictable challenges. Every map tile now holds a surprise — encounters, evolving terrain, and environmental shifts — making each step into the unknown more immersive and unpredictable. A comic-book-inspired storytelling system replaces the traditional chapter structure, making the story more immersive, easier to follow, and filled with branching choices that shape your journey. New explorers, arcane relics, sinister events, and chilling encounters breathe fresh life into Machina Arcana, ensuring that every journey is shrouded in mystery and peril. Vivarium is fully compatible with all previous scenarios and editions of Machina Arcana. — Description from the publisher
