 A major element of "CthulhuTech" is fear and insanity.All alien monstrosities have a fear factor that forces a Tenacity roll – should the player fail, he or she will be scared or panicked by the presence of the monster, which may have scarring effects on the character's psyche.As well, coming into contact with aliens and demons, performing sorcery, utilizing psychic abilities, or witnessing horrible events, could lead players to gain points of Insanity.
