This makes for a never-ending journey in the world of Terraria. As you move from one world to another, you will need to continue crafting tools that you can use for that world. Whether you play Terraria as a single-player, in an online player versus player or in co-op, your strength will rely on equipping yourself with stronger weapons, armor, and accessories. The result is a dynamic gaming experience for each player. You can search for treasure and raw materials, fight bosses, or construct your own city. Terraria is an action-adventure sandbox game where you set your own goals.
