About SIDE EFFECTS
Side Effects is a tense, turn‑based medical roulette game where up to four test subjects compete to outlive each other. Each round presents a selection of pills—some helpful, some harmful, and some causing instant death—requiring careful resistance management.
Between rounds players can choose experimental items such as vaccines or mouth clamps to shift odds. The title offers a single‑player experience and a multiplayer mode for 2‑4 players, with online PvP and accessibility options like custom volume controls and a mouse‑only mode.
01 / THE GUIDE
Game Premise
Side Effects pits up to four test subjects in a twisted medical trial where only one can survive. The core objective is to outlast opponents by managing resistance against unknown pills.
Each pill can affect mind or body in unpredictable ways, and reaching zero resistance ends the player’s participation. The hidden effects create tension each round.
- Observe early pill outcomes to gauge risk.
- Prioritize resistance when it drops low.
02 / THE GUIDE
Pill Types
The game includes six distinct pill types that appear each round. Some provide benefits, others are harmful, and a few cause instant death.
Because effects are hidden until consumption, players must decide whether to gamble on a pill or conserve resistance for later rounds.
- When resistance is low, favor pills that have shown benefits.
- Avoid unknown pills if you are near zero resistance.

Experimental Items
Between rounds, players can select from a range of experimental items and treatments, including vaccines and mouth clamps. These items are intended to shift odds in the player’s favor.
Using items adds strategic depth beyond pill selection, allowing players to influence future outcomes and manage resistance more effectively.
- Deploy items that shift the odds in your favor before a high‑risk round.
- Consider how items might combine to affect pill odds.

Multiplayer Mode
Side Effects supports a multiplayer mode for two to four players, enabling online PvP where opponents bluff, adapt, and use every tool at their disposal.
The competitive setting adds a psychological layer, as each participant tries to outlive the others by managing resistance and manipulating item choices.
- Watch opponents’ resistance levels to anticipate their pill choices.
- Notice opponents’ item choices that may hint at their strategies.
