The Slug Defender is a 12 gauge shotgun in Syphon Filter: Omega Strain which uses slug ammunition.
"The Slug Defender is a durable pump - action shotgun that has a breech partially locked by recoil. Although the user must pump this weapon to reload the ammo, the locked breech gives the weapon fast and easy operation and long range accuracy."

In game uses
The Slug Defender is unlocked by gaining the rank of Field Analyst Specialist, and is a very basic weapon. It is capable in close quarters battles, but users suffer from long-range impotence with such a weapon. One should trade it out for a better weapon as soon as possible.
