Kaiju Siege: Kaisen Expansion is an expansion for Kaiju Siege released in 2021 for 1 player, 15–20 minutes per game, and ages 12 and up. It was designed by zombie homer and its main mechanics are Dice Rolling.
Injured kaiju started to retreat to the ocean. Your shogun will have none of that, and has ordered a pursuit to end the kaiju siege once and for all. You readied your atakebune warship and prepared your troops for a battle at sea. This expansion for Kaiju Siege comes with an alternate game board and 4 new kaiju. Battles may now take place out at sea, where your workers run the risk of falling overboard, and the kaiju can damage your ship's hull and cause it to spring a leak. This understandably introduces a new losing condition - your ship can sink! The four new kaiju are also compatible with the game board from the base game. The base game is required in order to play this expansion.
Kaiju Siege: Kaisen Expansion supports 1 player according to the catalogue. This is the publisher’s listed player count, so the game is designed for exactly that number of participants. Variants for other group sizes, if any, are described in the rulebook of your edition, so check it before setting up a different configuration.
The listed playing time for Kaiju Siege: Kaisen Expansion is 15–20 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 Kaiju Siege: Kaisen Expansion 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.
