Mansions of Madness: Second Edition – Altered Fates is an expansion for Mansions of Madness: Second Edition released in 2018 for 1–5 players, 90–120 minutes per game, and ages 14 and up. Its main mechanics are Hand Management, Area Movement, and Dice Rolling.
Lady Helena, the woman who hired you, is abducted through a polychromatic portal before your eyes! With the portal closing and only moments to act, you must decide who will follow into the unknown. Will you be able to work together even while torn apart? Altered Fates challenges investigators like never before by dividing the team across two maps that are in play simultaneously. The first is a proper 1920s mansion, like those you have come across in previous investigations. The second, however, is the future of this home— now an abandoned, boarded-up building. Each map presents its own series of challenges, with the investigators in the present directly affecting the investigation of their companions in the future: an item tucked beneath a loose floorboard may be found later in the same hiding place, or a rescued captive may be able to return to the mansion in the future.
Mansions of Madness: Second Edition – Altered Fates supports 1–5 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 Mansions of Madness: Second Edition – Altered Fates is 90–120 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 Mansions of Madness: Second Edition – Altered Fates 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.
Mansions of Madness: Second Edition – Altered Fates has a complexity rating of 2.8 out of 5 from BoardGameGeek players, which makes it a medium-light game.
