The line comes from Darkest Dungeon, the dark fantasy dungeon crawler by Red Hook Studios, where the Ancestor narrates combat with grim, sardonic commentary. 'Continue the onslaught, destroy them all' is one of his battle prompts, encouraging players to press an advantage rather than retreat. Clips of the narrator became popular with players sharing gameplay moments, and the line spread through edited videos and soundboards as a shorthand for ruthless momentum. It endures because the delivery is instantly recognisable and fits any scene where someone refuses to back down.
