We've released the second major update for the S.E.M.I. – Side Effects May Include demo, packed with new content, mechanics, and improvements. Without further ado, let's get down to business.

New features for the inmates of our favorite nuthouse

  1. We heard your feedback and added a single-player mode.

    • Here's how it works: if you're alone in the lobby and start a run, you'll be taken to a location designed for solo play. The game doesn't prevent other players from joining you during your escape on this map.

  2. Added 4 new rooms to the group escape. Will you manage to complete this obstacle course without getting fried by the traps?

  3. New Ability – 'Pyromaniac'. You can launch a fireball, just like a sorcerer... only with deviations. But be careful: the size of the fireball is not up to you! Your teammates will love this gift.

  4. Vendor. That very one who stood in every hallway, annoying you by refusing to give you pills. You can now collect candies on the map and use them to buy even more pills.

  5. Settings Interface. We've standardized the settings layout and added a new 'Controls' tab, allowing you to learn the game's main functions without memorizing hints on school boards in the lobby.

  6. Simplified the object throwing system. When charging a throw, release any button (LMB or RMB, or both at once), and the object will fly where intended.

  7. Ability – 'Meatball'. We've fundamentally reworked this ability's mechanics. Now you can:

    • Launch yourself like a mad projectile towards enemies or... your own teammates.

    • Your teammate can pick you up and aim your flight in the right direction.

Minor Improvements

  1. Added a HUD icon that prompts you when you can pull a stuck teammate out of the floor or a wall. And yes, it's not a bug, it's a feature :)

  2. Updated the visuals of several objects on the maps.

  3. Reworked the visual design of the main menu.

  4. Added a bunch of new sounds.

  5. Fixed several bugs.

The updated demo is available for download now!

Add the game to your wishlist and follow the updates – side effects are guaranteed!
