  3. Take a seat

    Each player presses a button on their own controller to join and takes a spot on the screen. Pick a layout that fits your players.

    Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.

  4. Launch and connect

    Press Launch: Nucleus opens one copy of Human: Fall Flat per player and lays the windows out on your screen. Then link them in game, usually one player hosts a LAN or online session and the others join it. The handler notes say how.

Handler notes

Read the handler notes in the UI.

The game already has native split-screen for 2 players max, with this handler you can play with 4+. Launch only two instances in horizontal split-screen for 4 players, 2 players in each instance using the game's native split-screen, you can add a local player by pressing start in the second and fourth gamepads respectively. If you only want one player per instance select No in the Nucleus UI option for native splitscreen before pressing Play. Host an online game in one instance and join in the others. If you use keyboards and mice press the END key to lock the input for the instances to have their own cursor. You can also use CTRL+Q to close Nucleus and all its instances when the input is unlocked.

To add workshop skins and levels after launching once via Nucleus go to the instances folders and in Human_Data\Plugins\steam_settings\mods\ add the mod folders. You can get the workshop mod files using this site: http://steamworkshop.download/download/view/1873065129 Download them then extract the zip and place the folder inside the mods folder I mentioned.
