QUAD M03: Sonic Shotgun
Different threats require different tools. The deluge handgun is awesome but the sonic shotgun delivers you from evil.
Simply swap-out the 'deluge' liquid magazine and attach the shoulder stock with adjustable ergonomic shoulder cushion, extra powerpack, and additional ball ammo mag.
Interchange the single-shot pistol barrel for the double barrel and duel magazine. The supersonic speaker blasts those nasty unwanted germs off anything-EPIC!
