The Battle at Kemble's Cascade: Cetus is an expansion for The Battle at Kemble's Cascade released in 2015 for 1–5 players, 75 minutes per game, and ages 13 and up. It was designed by Anders Tyrland and Olle Tyrland and its main mechanics are Hand Management, Simultaneous Action Selection, and Grid Movement.
The Battle at Kemble's Cascade: Cetus features a huge Lovecraftian eel that serves as an intermediary boss level during the game. Cetus appears following the asteroid stage and sits at the top of the screen (as a temporary sixth row) while the wormhole stage scrolls normally below it. At the beginning of each round, Cetus draws from its own "boss" sector card deck, revealing either a wormhole or a burst bomb. To determine which column receives this payload, draw from the regular sector card deck and match its special icon to the corresponding boss segment. Cetus sticks around long enough to dump two bombs and two wormholes onto the star field, then it takes off. This beast is worth a fair number of points and bellonium, but its head and belly are immune to Gamma, so you need alternative methods to take those out.
The Battle at Kemble's Cascade: Cetus 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 The Battle at Kemble's Cascade: Cetus is 75 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 The Battle at Kemble's Cascade: Cetus for ages 13 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
