Take a seat
Each player joins with their own keyboard and mouse 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 Arctico 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

IMPORTANT: when the game starts, go into settings and turn off fullscreen in the first launch of that instance.

Also the game is pretty scuffed even tho it's on version 2.4 (as of release), some problems aren't things Nucleus can fix.
