In the level's opening scene, just before Rtas 'Vadumee says "And continue our march to glorious salvation!", another subtitle will appear for a split second. Right when the Elites say "We shall grind them into dust.", the subtitle will say "- scrape them as excrement from our boots!"
Some think the developers took that particular line out because Elites do not actually wear boots, as they have hoofs at the end of hocked legs.
Please note that you must have the subtitles in the options menu set to the on position or have the Black Eye Skull activated.
