Side Effects is a turn-based strategy game that thrusts players into a high-stakes medical trial where survival hinges on risky decisions. Developed as an indie title for PC, it blends elements of chance and tactics in a setup reminiscent of psychological duels, where outlasting opponents means navigating a deadly array of pills and experimental tools.
Gameplay
In Side Effects, the core loop revolves around selecting from a lineup of pills each round, with no prior knowledge of their effects. Some boost your resistance, others drain it, and a few can end your run instantly. Resistance acts as your lifeline; letting it drop to zero spells death. Between rounds, you pick from experimental items that alter the dynamics, such as vaccines to counter harmful effects or mouth clamps to limit pill intake. Opponents across the table employ bluffs and adaptations, turning each match into a battle of wits and endurance.
The game emphasizes resource management and prediction. With six distinct pill types, players must weigh risks based on visible clues and past outcomes. Visual changes to characters intensify as pills take hold, reflecting deteriorating states that add to the tension. Matches build in complexity, demanding careful strategy to outlive rivals.
Game Modes
Side Effects offers a single-player mode where you face AI-controlled opponents in a solo trial, honing skills against programmed tactics. This setup allows for practice without the unpredictability of human players.
The multiplayer mode supports 2 to 4 players online, creating longer, more intense sessions as participants vie to be the last one standing. Here, social elements like bluffing come into play, making each decision feel personal and fraught with deception.
Items and Strategy
Over 15 unique items provide ways to tilt the odds, from protective gear to disruptive tools that affect opponents. These choices occur between rounds, letting you experiment with combinations that suit your playstyle. The roguelike influence means each run can unfold differently, encouraging replayability through varied builds.
Recent updates have introduced new items, expanding the tactical depth and keeping the meta fresh. Players often discover synergies that turn seemingly dire situations into comebacks.
Is It Worth Playing?
With an 84% positive rating from 715 Steam reviews, Side Effects has garnered very positive reception for its innovative take on strategy and risk. The game receives ongoing support through updates that add items and refine balance, maintaining engagement well into 2026.
If tense, turn-based confrontations with elements of chance appeal to you, especially in a compact indie package, this title delivers sharp thrills. It's particularly suited for those who enjoy quick sessions or multiplayer mind games, though it may not satisfy players seeking expansive narratives or action-oriented gameplay.
