The Subsurface Resonator is a buildable featured in Buried and Borough. The idea of it is that it blasts the zombies away. However, a Turbine is required to activate the Subsurface Resonator. It supposed to function long and powerful, however, after a patch, the time it works is reduced.
The Subsurface Resonator is needed to get the Death From Below achievement, as well as playing a key role on the Maxis side of the Easter egg Mined Games.
