Custom Non-Playable Characters (also known as Custom NPCs or Homemade NPCs) are Non-Playable Characters made by the users of Total Jerkface. Jim made a news blog releasing the characters available at the time . This was in the form of a .zip containing a .fla file for Flash CS3 and up of the characters available at the time. Jim was interested in letting users create their own character that would be added into the game. However, none of the user-made characters had made it into the game.
Besides modifying these characters, the player can make false custom NPCs with the level editor, usually made with the poly tool or art tool. As these aren't true characters, they are not capable of blood, gore or ripped off body parts.Jason said that if the player were to make one, it should be for their own amusement.
