Talk about an application that lives up to its name. In “Insanity,” you find yourself smack dab in the middle of a terrifying mental hospital, engaging in underground fights with other players in the name of survival. You’re also supposed to earn whatever money you can scrounge up by assisting doctors and taking control of certain areas of the hospital. With a genuinely creepy atmosphere, nightmarish characters and showdowns that will leave you itching to survive, PlayFlock's terrifying creation isn't exactly for the meek of heart. That said, if you love horror movies, give it a go.
