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 Terraria 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.

About Terraria

Dig, fight, explore, build! Nothing is impossible in this action-packed adventure game. The world is your canvas and the ground itself is your paint. Grab your tools and go! Make weapons to fight off a variety of enemies in numerous biomes. Dig deep underground to find accessories, money, and other useful things. Gather resources to create everything you need to make the world your own. Build a house, a fort, or even a castle. People will move in to live there and perhaps even sell you different wares to assist you on your journey. But beware, there are even more challenges awaiting you... Are you up to the task?
