According to the Strategy Guide by Alex ErinsEdit
"Duke will run into these swine in every time period. Although Duke will find them dressed as L.A.R.D. Cops, Sheriffs, Court Guards, and even wearing togas as he travels through time. They have the same capabilities in each time period. Pigs carry a combat shotgun. When Duke shoots them, they may drop some ammo, or a shotgun. They also will drop their used armor. So don't think of them as enemies; think of them as walking weapon caddies"
According to the game manual: Edit
"Mutated human police forces used by the Alien invaders to dominate the human populous in an invasion zone. These piggish adversaries are both tough and dangerous, armed with the short-ranged but deadly shotgun."
SummaryEditThey were the first ones to appear in the game to fight before the other aliens. They're also the only enemies that appears in other games and cutscenes.
==Duke's Quotes to them after Kill== "Mmm, I love the smell of bacon in the morning." "Who wants bacon and eggs?" "You want some of this?" "Hmm, I guess pigs do fly!" "Mmm..bacon bits!" "Bringin' home the bacon!" In the level Family Jewels as Duke opens the Von Nukem Castle drawbridge: "Little pig, little pig, let me in, or I'll huff, and I'll puff..and I'll kick your ass in!"
They can be easily detected by making any type of noise, (i.e. jumping, bumping into a wall, firing a weapon.) as they will make a distinct sound, announcing their alarmed state. This strategy is especially useful on higher difficulties and works with Draks as well.
