🚨 DEMO MODE ACTIVATED 🚨

Did someone order pills? We’ve already scattered them all over the floor!

The S.E.M.I. — Side Effects May Include demo is live on Steam, and now you have the chance to escape the clinic, tossing guards aside, popping pills, and tackling twisted puzzles.

The demo is out now on Steam

Watch the trailer on YouTube

What to expect:

  • Co-op for 1–4 players with a touch of madness

  • Pills with powers: useful, strange, and completely insane

  • A madness meter that decides when your character loses it

  • Rooms filled with enemies, traps, and lobotomy puzzles

  • Fights against orderlies and other “fellow inmates”

  • A personal diagnosis after every escape

We’ve put a lot of effort into making the demo as chaotic and fun as possible. We hope you’ll have just as much fun playing it as we did creating it.

Join our Discord - you can ask questions, report bugs, or just chat with other patients. Steam forums are always open too.

What’s next?

  • New rooms to escape from

  • Unique conditions in rooms

  • Even more pills, even more side effects

  • A vendor to trade lollipops for pills

  • More wild diagnoses

And, of course, more chaos and plenty of fresh meme material ːsteamhappyː
