Antidote: Lab Alliance is an expansion for Antidote released in 2018 for 3–9 players, 20–40 minutes per game, and ages 14 and up. It was designed by Dennis Hoyle and Jonathan Logan Clark and its main mechanics are Trading, Simultaneous Action Selection, and Memory.
Description from the publisher: “DANGER, DANGER!” The unwavering emergency voice on the loudspeaker reminds you again-and-again of the deadly airborne toxin contaminating your lab. If you’re going to survive, you’ll need to find the antidote…fast. The flash of the warning lights gives you just enough visibility to find your teammates and compare notes about what the antidote could be, but you suddenly realize there may not be enough of the antidote for all of you. Will you be willing to give-up your dose so your teammates can live? Antidote: Lab Alliance expands the world of Antidote with five new ways to play including support for up to nine players, team-play, new turn actions and special cards, and sinister new Lab Romance characters.
Antidote: Lab Alliance supports 3–9 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 Antidote: Lab Alliance is 20–40 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 Antidote: Lab Alliance 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.
Antidote: Lab Alliance belongs to these categories: Card Game, Deduction, and Expansion for Base-game. Its main mechanics are Trading, Simultaneous Action Selection, and Memory. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The credited designers of Antidote: Lab Alliance are: Dennis Hoyle and Jonathan Logan Clark.

The catalogue lists Antidote: Lab Alliance as an expansion for Antidote. Expansions add new content, rules or scenarios to the base game and usually cannot be played on their own, so you need Antidote to use it. Check that your edition of Antidote is compatible, as some expansions were revised between editions.
