Knott's Berry Farm to add 3 new mazes to Halloween Haunt

This year marks the 39th annual Knott's Scary Farm and will feature 13 mazes and four scare zones. The first of the new mazes is the Invasion Beneath which will have the military battling creatures from Earth's core. Invasion Beneath will be replacing Black Widow's Cavern. The second new maze is Endgames: Warriors of the Apocalypse, a arena where gladiators will meet for battle. It will be replacing the maze Labyrinth. The final new maze is Delirium, a place somewhere between nightmare and insanity.

Of course everyone's favorite mazes will be back including Virus Z, Terror of London, Uncle Bobo's Big Top of the Bizzare in 3-D, Fallout Shelter, and Doll Factory. Halloween Haunt 2011 runs for 27 nights starting September 23.
