Side Effects: Booster Shot

About this expansion

Side Effects: Booster Shot is a 2023 card game expansion for 2–8 players, with a play time of about 30 minutes, in which players race to treat all the diseases in their psyche using drugs and therapy.

As a take-that card game, Side Effects brings together drug use, personal demons, wild episodes, and more. Its central race gives players a clear objective: treat every disease in their psyche while navigating the effects of the cards in play.

Booster Shot is the first expansion pack for Side Effects, created to expand the pain and the pleasure of the experience. It introduces additional cards and actions that add functionality while bringing exciting new dynamics to the game.

• New Disorders to add to the game’s psychological challenges
• New Drugs to broaden the available card content
• New actions that provide additional functionality

These additions give the expansion a direct connection to the original game’s race to treatment and its confrontational take-that foundation. The result is a larger set of possibilities built around drugs, therapy, and the diseases players are trying to treat.

With support for two to eight players and a listed play time of 30 minutes, Side Effects: Booster Shot offers a compact expansion for groups who want to extend the game’s themes and add new ways to play. It brings more Disorders, Drugs, and actions into the same race through the psyche, adding fresh functionality and new dynamics without leaving behind the core premise of treatment.
