About SIDE EFFECTS

SIDE EFFECTS - about the game

Four test subjects enter a twisted medical trial on PC. Only one survives the turn-based roulette of pills that alter mind and body. Players select from helpful, harmful, or deadly options each round, managing resistance to avoid instant death at zero. Between rounds, grab experimental items like vaccines or mouth clamps to tip the scales. Opponents bluff and adapt in multiplayer matches for 2-4 players, or tackle single-player mode. Strategy fans who relish tense risk management and outlasting rivals will keep coming back for the 15+ unique items and six pill types.

Up to four test subjects. One twisted medical trial. Only one leaves.

Welcome to Side Effects: a tense, turn-based medical roulette game. Each round you'll be presented with a selection of pills. Some are helpful, some are harmful, and some mean instant death. You never know what you're about to consume or what it might do to your mind or body. Winning means outlasting – AKA, outliving – your opponent across the table.

Resist

Every pill impacts your resistance. Manage it wisely: zero resistance means death.

Experiment

Between rounds, you can choose from a range of experimental items and treatments that can shift the odds in your favor, from vaccines to mouth clamps.

You’re not alone

The other patient wants to outlast you. They’ll bluff, adapt, and use everything at their disposal to keep breathing one dose longer than you.
