Thumper

The Thumper is a deployable device that creates loud, pulsing noises in order to distract Ice Worms. Ice Worms will prioritize the noise coming from Thumpers over other sources of noise, allowing for the player to traverse through Ice Worm territory as loudly as they wish, without drawing attention. This also means that players will be able to use drills without the noise attracting worms.

Trivia

 * According to developer David Kalina, the idea of the Thumper is "shamelessly stolen" from the 1965 sci-fi novel, Dune.
