Eclipse: Shadow of the Rift is an expansion for Eclipse: New Dawn for the Galaxy released in 2015 for 2–6 players, 120 minutes per game, and ages 14 and up. It was designed by Touko Tahkokallio.
Description from the publisher: The Ancient Uprising has been put down, and a fragile peace again holds in the galaxy...but suddenly, everything changes. Several new factions rise to disturb the status quo. The Unity nanomachines bend energy and matter to their will. The Shaper ships tear the spacetime fabric apart, while insignificant Octantis factions take a developmental leap after leap forward. It almost seems like the base laws of the universe no longer apply. Eclipse: Shadow of the Rift introduces several new mechanisms to Eclipse, including Time Distortion, Evolution and Anomalies, as well as several new Rare Technologies, Developments and Discoveries. It includes two new player boards with three new different alien species from which to choose. Due to its modular design, you can use all of these additions or just some of them in any game of Eclipse according to your preferences and play style. The expansion does not require the Rise of the Ancients expansion, but is fully compatible with it. As the shadows unfold from the rifts of spacetime, can your civilization stand unbroken?
Eclipse: Shadow of the Rift supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Eclipse: Shadow of the Rift is 120 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Eclipse: Shadow of the Rift for ages 14 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Eclipse: Shadow of the Rift has a complexity rating of 3.9 out of 5 from BoardGameGeek players, which makes it a heavy game.
