Nightmare mode, 1 node on a planet becomes nightmare difficulty after completing all said planets mission nodes till there are no blue diamonds(unfinished) missions. Then a white diamond appears around a mission node with a swirl over it. All nightmare missions drop the same mods so you must keep hitting them till you get that modes mods.

(nightmare missions are not dark sector missions and dont drop extra loot) they dont even have weapon bonuses. Just harder with simple handicaps like energy vampirism(kill to gain energy) No shield mode, Death detonation mode.
