[STAGE #2:] Loss in appetite, complete loss of interest, slight hostility, "strange" eyes. [STAGE #3:] Suicidal tendencies, violent, weight loss, mutation, memory loss. [STAGE #4:] COMPLETE CORRUPTION. Homicidal, Hostile and dangerous to be around. As the parasite takes over the victim will begin to lose its voice.
