You’ll be managing and overseeing a variety of specialized Steambots and buildings as you build your city inSteamworld Build, and it takes time for them to do their thing. Materials need to be excavated, transported, refined, and sent all over your city. In the mines, you have to get Guards to deal with hostile enemies.

Maybe you wish your Steambots delivered items just a bit faster or that you could speed up the production of crucial materials like Sheet Metal. It’s all possible, and more, if you invest in Item Attachments. We’ll go over what item attachments are, how you can get them, and all the types available for you to obtain.

A list of many different item attachments such as Warehouse Items and Miner Items owned by a player in Steamworld Build.
