About
S.E.M.I. is a cooperative online game about escaping from a special clinic. Here, you and up to 3 of your brainless loyal friends play as patients, fighting staff and other patients while stumbling into all sorts of unexpected situations. Brawls, side-effect pills, and brutal platforming will absolutely challenge your clumsy friends’ hands sense of teamwork. Expect obstacles, puzzles, deadly traps, and rooms where a single wrong move can knock out the entire squad.
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!

I honestly love how goofy this game is. It is so much fun! I love the different 'side effects' and the customisation of the characters. The puzzles are funny too, I don't find them stressful. All in all I find this is a nice chill game!
Played this with my wife and we had a surprisingly good time. It can be a bit difficult at first, but that actually makes it more satisfying once you get the hang of it. The overall theme of the game is completely crazy (sorry… couldn’t resist the pun 😅), and the unpredictable abilities and side effects make every run feel chaotic in a fun way. I really like the customization options and the general design of the game. The art style and characters are pretty cool, and unlocking new outfits and decorations adds a nice extra layer to the experience. The idea behind the game is also quite original. Running through rooms, dealing with traps, fighting enemies, and dealing with random pill side effects keeps things unpredictable and entertaining the whole time. The levels and challenges keep you busy and engaged, especially when playing together. Overall, a fun and weird co-op experience that’s great to play with friends or your partner.
