Beware!! MTV turns Tuesdays into a night of chills and thrills with the premiere of new series "Room 401," as well as an extended season of the popular stomach-turning series "Scarred" -- all beginning July 17 at 10pm ET/PT. Also premiering that night is the one-hour special, "Scarred: The Worst of the Worst."

Viewers are asked to enter the mind-blowing journey through the weird, absurd and shocking world of illusion in the new series, "Room 401." The show sweeps unaware victims into the center of mini horror movies that play out live in front of their eyes. From the reanimation of the dead, to chain-saw mishaps, to sinister sushi experiences, each episode will contain four "scares" sure to tingle the spine. Featuring some of the most talented, up-and-coming illusionists, "Room 401" will make viewers scream, jump and even laugh... uncomfortably. In this age of CGI and edit room after effects, "Room 401" unfolds live. We don't manipulate the film... we manipulate the mind.
