Trog is the common name for humans that have become infected with the Troglodyte Degeneration Contagion (TDC). Trogs reside in the Pitt. Due to the contagion being endemic to the town, approximately 20% of the populace have transformed into these wild, chattering monstrosities, hiding in darkness and attacking anything on sight. Study shows that children born in TDC-active areas virtually have a 100% degeneration rate and become feral within weeks of birth. They will kill friends and loved ones. They say lines like "Kill it!", "Meat!", "Hungry!", and "Food!" when attacking, and "Hurts!", "Pain!", and "Why?" upon being injured. Some can even be heard muttering "...peace..." or "Thank you..." right before they die.
They will only spawn in the steelyard, power plant, and abandoned apartments; not in lit places such as Uptown. Trogs are weaker than standard humans; a basic trog is on par with a basic feral ghoul, and even the powerful trog brutes and savages are still only on par with standard raiders in terms of health. However, they are much faster than normal humans, have fairly powerful melee attacks, and rarely hunt alone.
These trogs are the smallest and weakest of the trog family. This type of trog will be encountered primarily at level 7 and below.
These trogs are the strongest and most powerful trogs in the Pitt. They are encountered rarely but are essentially trog brutes with slightly more health. Although only slightly tougher than trog brutes, trog savages have powerful melee attacks similar in damage potential to those of a giant radscorpion or mirelurk hunter.
Most trogs carry exactly one item. Bobby pins are very common, as well as single doses of chems and various miscellaneous items.
When talking to Midea in her quarters for the first time, the Lone Wanderer can ask either what a trog is or imply that it is a fish. They can also ask if they are like a super mutant, to which Midea will reply asking what a super mutant is.
↑The Lone Wanderer: "What happens to people who get sick?" Wernher: "It's hard to describe. It's nasty. And it affects everyone a little differently. But the longer you're there, the more it gets you. Some just get sick and die. Others go crazy, completely psycho. They live out in the city. We call 'em 'Wildmen'. And the worst... well... just hope you never have to see 'em. They turn into animals. They forget who they are. They just eat, sleep, fuck, and kill. But this cure, maybe it can stop all that." (Wernher's dialogue)
