Which digital format of S.E.M.I. – Side Effects May Include... should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

If I buy the account format of S.E.M.I. – Side Effects May Include..., will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Can I return a digital game for PC?

Some digital formats allow returns under certain conditions.

The store does not send my order and does not respond to support. What can I do?

Don't worry, we have the solution. We will handle it ourselves.

The final price is higher than indicated.

Many stores add payment fees, taxes,... in the cart. So be prepared to spend a little more.

I'm desperate: They don't send me the game, the store ignores me. I think I've lost my money.

Calm down, don't panic. Contact us and we will help you resolve it as soon as possible.

About S.E.M.I. – Side Effects May Include...

S.E.M.I. is a cooperative online game about escaping from a special clinic. Here you and up to 3 of your feeble-minded loyal friends in the role of patients fight with the staff and other patients and find yourself in unexpected situations. Teamwork is essential, as randomized events and experimental drugs will lead your party into unpredictable mayhem. Pop pills with your friends as you cooperate to gain your freedom.

Communicate in voice chat and arrange sabotage help your friends pass through rooms, get out of traps and fight with opponents! In your arsenal: close combat, physics, amazing abilities and ... imagination!

Take pills and get abilities:

Bipolar force is an invulnerable monster, then a helpless rag!
Laser astigmatism — two sights, one laser… Where will he shoot?
Stendhal syndrome — are you looking at a painting? Now you're hysterical and destroying everything around you!
Alice's syndrome is either tiny or gigantic — have time to adjust!

Madness is near! You and your friends can go crazy and start running, jumping and fighting, and your abilities will become uncontrollable. Do you want to take back control? Take the pills :)

Locations are randomly generated from rooms with changing gravity, traps, moving walls, and other "pleasant" surprises.

After a successful escape, you will receive a medical report: "The patient was stable until he started hitting the guards with a bottle. Diagnosis: Overmotivation" or something worse!

Unlock new costumes and decorations. Let each new escape be more stylish than the previous one!

Will you and your friends be able to escape... or at least not go crazy?

Welcome to the mental hospital! Here, your abilities are a lottery, and your friends can be the most dangerous opponents!

S.E.M.I. – Side Effects May Include... for PC starts at €2.16 at Kinguin, a Steam key, which is 72% under the €7.79 it costs on the official store.

That €2.16 already includes the AUGGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Just 4 stores stock it, 4 offers in all, so there is little here to push the price either way.

That puts it 11% under its average of €2.44 since 2025, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for S.E.M.I. – Side Effects May Include... now or waiting?

That €2.16 key has only just launched and is still coming down.

The Steam Key has dropped 17% since release, and only 259 days have gone by.
Over the last month it has come down another 17%.
Only 4 stores sell the Steam Key, and with that little competition the price barely moves.
Not counting today, the Steam Key has only been this cheap or cheaper on 74 days out of the 241 days on record: today you are close to the best it has ever cost.

If you can hold out a couple of weeks the Steam Key will probably drop a little further — although that is what usually happens, not a guarantee.

Worked out from 384 daily records of the Steam Key for S.E.M.I. – Side Effects May Include... across 4 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate S.E.M.I. – Side Effects May Include... in US?

All 4 offers are Global, so the code redeems on any account no matter where it was created.

So, which S.E.M.I. – Side Effects May Include... deal should you buy?
