To promote the album, the band embarked on their Hydra World Tour, which was originally planned to start in January 2014, but then was postponed so the band could polish the songs more before releasing the album and had a try-out show at the Effenaar, in Eindhoven, NL, in which sold out on the same day it was put on sale. The first official show happened on February 26, in Helsinki, Finland, and the arena tour passed primarily in Europe, covering a few summer festivals. Due to the great reception of "Hydra" in the United States, the band decided to tour again in North America, travelling from West to East coast and passing over twelve cities, being two in Canada and having some venues with sold out tickets. On May 2, the band announced through their Facebook page that they were going to record the concert at the Heineken Music Hall, Amsterdam, and the great part of the concert later appeared on the DVD "Let Us Burn - Elements & Hydra Live in Concert" together with some parts of the previous tour "Elements" 15th anniversary show. As the end of the European leg, the tour had an attendance of over 120.000 people.
