From Warhammer 40k - Lexicanum
(Redirected from Rad-Wave)
Rad Waves were monstrous weapons created during Old Night, that were later used heavily by the First Legion during the Great Crusade.
While such weapons as Rad Waves and Gene-phages were available for the Space Marine Legions to use, only the First Legion made common use of them. And even they only unleashed these weapons of Old Night to wipe clean the nests of enemies, the First Legion deemed too terrible to be faced in open battle.
