Need at least Mythic skull turned on. Thunderstorm recommended for the Covie squad. Spike nades are recommended over plasmas, especially if you have Cowbell enabled.
Floodgate (was played on Heroic difficulty):
0:00 First I show how to get rid of Arby from Floodgate if you like realism (simply backtrack to the room where the Cortana moment triggered, the room should be sealed when you head outside).
0:30 Now for the actual setup. Get up to a higher vantage point and headshot Flood combat forms without starting the Shadow of Intent cutscene.
2:28 Note that the SpecOps Elites deployed here already spawn with swords so you can't simply kill Arby for sword drops to give them to Elites. I give the Elites a Spiker while sticking them (for a sword pull) so I can take it back from them and save myself the trouble of having to backtrack to pick up another one.
2:31 Sometimes they might not survive the stick, especially if they're nearby a wall or object. Should this happen, revert.
3:46 If a Brute Shot was dropped, you can give it to the Elite Major or use it for melee. There's also a 100 battery sword at the elevator (4:54).
5:06 Taking the squad for a stroll. They are really good against Flood combat & tank forms!
Covie:
7:03 Pretty much the same as above, only this time you have plenty of checkpoints and you can just kill Arby a bunch of times for a sword instead.
9:30 Sword Elites can scarcely damage Hunters but they can send them launching around the tower, sometimes onto the elevator as seen in vid (10:30). Hunter battle is a good opportunity for Arby to do a sword pull (10:22).
