Brook City is a board game released in 2019 for 1–4 players, 45–120 minutes per game, and ages 13 and up. It was designed by Adam Sadler and Brady Sadler and its main mechanics are Variable Player Powers, Dice Rolling, and Cooperative Game.
A mysterious criminal element has taken root in Brook City. Known only as "The Syndicate," this collection of ruthless murderers, clever thieves, corrupt politicians, and dirty cops has given rise to a new era of crime. The Brook City Police Department needs the best of the best to clean up the streets of this once peaceful metropolis. So here's your gun and badge...get to work, officer. Brook City is a co-operative miniatures board game of blockbuster action for 1–4 cops. Taking on the roles of heroic cops inspired by classic action movie stars, players take their cop decks up against sinister criminal decks and cryptic case decks. Gameplay focuses on a sprawling game board depicting the mean streets of Brook City. Players must use their chosen cop's unique deck to race across the city—both on foot and behind the wheel—busting up their chosen criminal's machinations while simultaneously piecing together the clues to the chosen case. Brook City thrusts players into a world of big budget Hollywood action, where they can take down dangerous criminals, bust crimes with custom dice, commandeer a variety of vehicles, and solve complex cases inspired by classic cop stories. Brook City utilizes Adam and Brady Sadler's "Modular Deck System (MDS)," which they introduced in Street Masters. The MDS focuses on quick setup and elegant, card-driven gameplay, while allowing players to customize their game experience by mixing and matching fixed decks to create truly unique match-ups.
Brook City supports 1–4 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 Brook City is 45–120 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 Brook City for ages 13 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.
Brook City has a complexity rating of 3.0 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
