About Side Effects
Side Effects is a turn-based medical roulette game for up to four test subjects. Each round, you choose from a selection of pills: some help, some harm, and some cause instant death. You do not know what you are taking or how it will affect your mind or body. The aim is to outlast your opponent across the table.
Manage your resistance
Every pill affects your resistance. If it reaches zero, you die, so you need to manage it carefully.
Items and treatments
Between rounds, you can choose experimental items and treatments to shift the odds in your favor, including vaccines and mouth clamps. The game includes 15+ unique items and 6 pill types.
Game modes
Side Effects includes a single-player mode and a multiplayer mode for 2–4 players. Other patients bluff, adapt and use everything at their disposal to survive one dose longer than you.
