Sergei's Subwoofer

"Push back soundwave that also deals damage"

- In-Game Description

Sergei's Subwoofer is a shotgun featured in Battlefield Heroes for the National Army and was introduced with the Aliens bundle. The weapon is statistically and functionally identical as Steve's Sonic Boom for the Royal Army.

Unlike other shotguns, the Sonic Boom emits a wave of sonic energy once fired. This results in a sound wave that pushes back and damages enemy players.
