The Hammer is a tool that the player spawns with and can not be removed from the hotbar. The hammer is used to make repairs at a base, as well as (re)moving objects like tables and extractors.

When using the hammer, objects such as a table will be placed into the inventory. Objects inside a Storage Box will not be stored. If a Storage Box is full of Gold, the hammer will move the box into inventory, but the Gold will disappear.

The hammer can also be used to repair leaking walls in an abandoned base, but it consumes 2 Iron.
