The conflict is between the invading Orks under the leadership of the Ork Warlord Ghazghkull Mag Uruk Thraka and the Imperial world of Armageddon's defence forces under the joint command of Herman von Strab, Overlord of Armageddon; Commander Dante of the Blood Angels; and Imperial Commissar Yarrick.
Over 2 days, the bands Mütiilation, Judas Iscariot, Destroyer 666, Horna, Murder Rape, Ork and Trimonium played on a purpose-built stage in the western part of the wildlife park.
In the 1991 book Ere We Go (Subtitled "Space Orks in Warhammer 40,000") and in the Gorkamorka rulebook, the Snotlings were revealed to be the original form of the entire Ork species.
In its latest release by Hasbro Games, Chaos Gate was bundled with Final Liberation: Warhammer Epic 40,000, set in Games Workshop's Epic 40,000 game system that pitted the forces of Humanity against marauding Orks.
