Nightfall: Crimson Siege is an expansion for Nightfall released in 2012 for 2–5 players, 45 minutes per game, and ages 12 and up. It was designed by David Gregg and its main mechanics are Hand Management, Pattern Building, and Open Drafting.
Nightfall: Crimson Siege is an expansion for the deck-building game Nightfall, a game in which players draft Minions that they then send to attack and inflict wounds upon their opponents. Nightfall: Crimson Siege takes players to the final stronghold in Europe where humanity makes its last stand at the Vatican. Some familiar faces return to help the weary souls as they fortify the city and await the hordes of ghouls to come. Crimson Siege adds 24 minion cards (eight copies of each) and 30 "Summon" cards to Nightfall. Summon cards are a new card type in a standalone deck that allows players to summon more minions into play than ever before. Whenever a card with "Summon X" on it resolves its ability, you draw from the top of that deck and place a minion into play under your control. A variety of Ghouls are in the summon deck, and unlike other minions in Nightfall, when a Ghoul is destroyed, exiled, or otherwise removed from play, it goes back into the summon deck. Thus the supply of Ghouls to overwhelm your opponents will never run out!
Nightfall: Crimson Siege supports 2–5 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 Nightfall: Crimson Siege is 45 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 Nightfall: Crimson Siege for ages 12 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.
Nightfall: Crimson Siege has a complexity rating of 2.7 out of 5 from BoardGameGeek players, which makes it a medium-light game.
