Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We have a clear vision to the full version of the game, but we believe that the best way to create a truly engaging and awesome gaming experience is to work towards this goal together with the players community.
Early Access will allow us to:
- Show our game to the Steam community as early as possible, as we believe it is already fun to play;
- Gather feedback and add exactly the content players want to see in the game;
- Test and balance key mechanics together with the most engaged audience.

We are confident that only this approach will make "Side Effects May Include" a game that remains enjoyable to play with friends for a long time.”

Approximately how long will this game be in Early Access?

“We plan to release the full version of the game in spring 2026.”

How is the full version planned to differ from the Early Access version?

“In the full version of the game, we plan to add new enemies, locations, abilities, side effects, and alternative game modes. We also want to expand character customization mechanics and add enhanced meta-progression.”

What is the current state of the Early Access version?

“Currently, the game already features the main cooperative and solo escape mode, which includes 25 levels, 12 abilities, 12 side effects, character customization, 8 types of traps, and 5 puzzles.”

Will the game be priced differently during and after Early Access?

“Yes, we plan to implement a one-time price increase when the game leaves Early Access, as the game will feature significantly more content and mechanics.
Additionally, this is our way of thanking the players who participate in Early Access and help us make the game better and more engaging.”

How are you planning on involving the Community in your development process?

“We already have a Discord server where we actively communicate with players, and we also maintain a Telegram channel where we conduct polls and respond to player comments.
Additionally, we plan to engage with users through the reviews they leave on the Steam platform.”

About This Game

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!
