About SIDE EFFECTS

✦ AI summary

SIDE EFFECTS is a turn-based survival game where up to four players compete in a deadly medical trial by choosing pills that either heal, harm, or kill while managing their resistance to stay alive longest. Bluff your opponents, deploy experimental treatments between rounds, and adapt your strategy to outlast everyone else in this tense game of medical roulette.

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.Would you like to participate?

This trial includes:

  • A single player mode
  • A multiplayer mode (2-4 Players)
  • 15+ unique items 
  • 6 pill types to test

✦ AI summary

SIDE EFFECTS is a Buckshot Roulette-style game with quirky mechanics and special candy elements that works best as a casual time-waster with friends, though it has a somewhat odd AI that doesn't always understand player input. Players find the gameplay and audio decent overall, with decent graphics and low system requirements, though opinions are mixed on whether it's worth playing depending on your friend group and tolerance for mid-tier party games. Most reviewers suggest it's fine if you need something to do for an hour but acknowledge it's solidly average entertainment.

Honestly just an alright game, as per usual with friendslop you need a good friend group, and personally that means that this game was potentially the worst game I've ever played, but if I had better options in terms of my ability to play with more amicable folk, trust me... I WOULD 8/10 RECOMMEND

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
