The foursome, veterans after 30 years in the business, join their countrymen Destruction and Sodom on the line-up for the three day festival.
Black metallers 1349 are set to make their Bloodstock debut, and Wolf return to Catton Hall to promote their forthcoming album, 'Legions of Bastards'.
Nemhain, Def Con One and Survivors Zero have also been added to the billing on the Sophie Stage.
