Since 2012 Europa-park had been teaming up with Leisure Expert Group for the production of the haunted houses for their Halloween event. In the initial years, this event was called Halloween Horror Nights, however in 2017 Europa-Park created a new Halloween concept called Traumatica. The overall concept is a post-apocalyptic atmosphere where multiple groups battle each other to reign over the wasteland.
For the first year of Traumatica all previous haunted houses were replaced with new houses: The Fallen, Ghouls, The Pack, Shadowborn and The Resistance, of which the first three were designed and produced by us. Over the years, the overall theme in the houses stayed the same, yet the houses were adapted with evolvement in storylines. In 2019 Ghouls was completely re-designed within the same theme, as well as major upgrades to the remaining houses.
