About the game

What you do in a play session

If you are already a fan of the 20 Strong system, get ready to dive deep into the human mind with the Etherfields expansion. Here, the challenge isn't just about rolling dice; it's about navigating a dreamscape that shifts as you make decisions. The standout feature of this box is the legacy-style aspect: the cards you flip during gameplay don't reset, they shape your deck for future sessions. It’s as if the game has a memory of its own, recording every step you’ve taken in the dream world.

Gameplay centers on managing influence resources. By spending them, you bolster your dice pool, enabling bolder maneuvers and access to special actions in evocative rooms. The freedom to use these actions whenever you see fit adds a refreshing strategic layer, allowing for creative combos that can be the difference between defeating a hidden boss or being consumed by the nightmare. It’s an intense experience, tailored for solo players who enjoy seeing the cumulative impact of their choices over time.

Etherfields captures all the surreal atmosphere fans of the original series expect, adapted for the agile and compact dynamics of the 20 Strong system. You’ll need plenty of cunning to balance your wrath and awareness while unraveling the secrets hidden in the darkest corners of the deck. If you are looking for a solo challenge that rewards long-term planning and continuous exploration, this expansion is a must-have. It’s a game that invites you to return again and again, not just to win, but to see how your deck has evolved and what new dangers you can overcome. Ready your dice; the journey through the dream is just beginning.
