Worms are underground enemies inSteamWorld Build. They snatch nearby workers, chew them up, and wait for new prey. Dealing with these monsters becomes inevitable when you try to explore the Marshy Ruins’ secret areas, as they block the path. But the problem isguards and traps are ineffective against Worms. They seem to be undead creatures lurking from the hellish bedrocks. This quick guide explains how to unlockthe necessary machinery to kill Worms. (Yes, there are specialized items in the game to get rid of killer insects.)
How to Defeat Worms
To kill Worms in SteamWorld Build,construct a Thumper. Thumpers are defensive machines that keep underground enemies away. When there is a Thumper in the area, Worms can’t attack Steambots and will hide underneath the mine.
Building at least one Thumper is crucial for getting the Manic Mechanic Achievement.

How to Unlock Thumper
You must reach Milestone Level 11 to unlock Thumper. This requires getting at least 80 Aristobots bysatisfying the needs of Engineers. After that, you can build a 3x3 Armory which allows building Thumpers.
How to Spot a Worm
You can identify a Worm’s hole by theyellowish tail sticking out of the ground. Look for a pile of dirt in the abandoned parts of the map with a glowing tentacle waving over it.
Each Worm can swallow one Steambot per minute. But their reach is limited. Basically, they can only eatworkers who pass by them. If a Worm is chewing a bot, other miners can walk past it with no issue. However, as soon as the first bot is digested, the Worm will look for new victims.

Worms are the main enemy in the Marshy Ruins. It’s best to prepare for exploring this area in advance by unlocking the Thumper and Armory.
