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.
Launch and connect
Press Launch: Nucleus opens one copy of Titan Quest Anniversary Edition 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.

Nucleus links the windows through the game's own LAN or online mode; the handler takes care of it.

Handler notes

Tested and working with latest legit Steam version.
Launch your main game at least once before running the handler so that the game's config files get created.
Split-screen setup guide. Steam needs to be opened.
If the instances move to the center or do not position correctly click outside the game's windows and use the Nucleus shortcut CTRL+R to reposition the instances.
Host a LAN multiplayer game in one instance and join in the others.
Disable Steam Input in Steam for the gamepads to work and restrict correctly, note that the game sadly disables gamepad support if the game's window resolution is low (for example it disables gamepad support in resolutions like 960x1080, 960x540, 1920x540 etc.).
If you use keyboards/mice after all the instances have launched, resized and positioned correctly, press the END key once to lock the input for all instances to have their own cursor, you need to left click each mouse to make the emulated cursors appear after locking the input. Press the END key again to unlock the input when you finish playing.
If you can not connect the instances via the native LAN try right clicking the game icon in Nucleus UI, select delete documents save path and delete the Nucleus players paths only not the original path (backup your instances save files before deleting them if you already progressed). You can also try moving Nucleus to your C: main drive, make sure your firewall or antivirus is not blocking the connection or any Nucleus files too.
Read the FAQ if you have any further questions and want to know more about Nucleus Co-op.
Connecting the instances via the game's native LAN in one PC was only possible thanks to the great work and fix by happyexpress. Big kudos to him.
