Subsurface Resonator

The Subsurface Resonator is a buildable in Buried for Call of Duty: Black Ops II. It is needed to get the Death From Below achievement, as well as the Maxis side of the easter egg Mined Games. It needs a Turbine to function and it blasts sound that kills zombies and distorts the screen. On zombies at a further distance, it will simply knock them back.

Stand
Found leaning up against the wall opposite of the bearings, down the hallway, towards the back door of the general store.

Speaker
Found on a counter before the cabinet. (Fridge)

Circuits
Found in a corner at the top of the staircase.
