About SIDE EFFECTS

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

Most common FAQs when buying SIDE EFFECTS for PC in digital format:

It is a key that will allow you to download the game SIDE EFFECTS on your PC from official download platforms.
As of 01/08/2026, in United States, the best price we have found in our selection of online stores that include the key for SIDE EFFECTS on PC is €2.46.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download SIDE EFFECTS to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought SIDE EFFECTS, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
