Completed it on my second try last night with a buddy and random from LFG, no chat with the random. Soft locked the boss so had to whipe and start again. First attempt we were there with around 3mins left on the timer. Second time was a little greasy and got there around 1 minute. Some tips for you are as follows. Pull the fireteam whoever gets there first if there’s still time on the clock by starting the boss encounter. Play your life, you don’t need a meta build. Stay on the floor in the back corner during the hive portion and then alternate up top above where you were during the hive, for the taken. At the end when you have to stand on the plate to close the door the boss still shoots at you and can whipe you. Use barricades, supers, rifts whatever you have for healing or DR. You should also spread out. It’s really not bad, don’t be deterred by all the people whining. Run it a couple times and eventually you’ll get it. Good luck, Merry Christmas.
