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 Castle Story 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

Multiple keyboards and mice only as the game lacks native controller support. Read the handler notes. Follow this guide if you want to play with controllers: https://docs.google.com/document/d/1Vwidk3pmH_X8IHWgEEbuX3MkUFRZBZu2yo__nfCKhjM/edit?usp=sharing
