Augen Auf [Open Eyes] is their 1st single and is from the 8th album, Wahrheit oder Pflicht [Truth or Dare] in 2004. The song appears to be about a demonic game of Hide-and-Seek. The video starts with a couple of young children walking down a deserted path. They are then seen going to a birthday party, a birthday party that is a nightmare for the adults present.
