Hostile Types
Sam's often get corrupted by PBBV and turn into a hostile type of Sam, such as a Greenie or Fader.
A subclass of hostile Sam is the Dead Employee, which is an employee of the Sam company that has been resurrected from the dead by the types shown above.
The hostile types have their own info providing more information below.
Greenies
These are a hostile type of Sam that will wander around the map looking for players, when they find a player, they will attempt to kill and eat the player so they can survive.

Faders and Dead Employees

These are similar to greenies, but they hide in dark areas of the map. They will often steal players souls right out of their bodies with a swipe. The soulless bodies of the players will often get up and become Dead employees/players. These walking corpses serve as guards to the fader and will tear players to shreds to protect the fader.
DEAD
This is a type of dead employee that there is only one of. It is the superior to the faders and commands them. It used to be a player, but after getting its soul taken, it ascended to a new level of power.
If you see DEAD, DO NOT GET SEEN AND HIDE.
