This is very do-able and you will eventually get it. It is still difficult though. I would recommend for primary weapon, like legendary auto rifle or pulse rifle, if you have Arbalest or something that can take shields down fast are good. For energy weapon you should use hard light. That was the main thing that helped me and my fire team when we did it. Hard light, or any fast firing energy weapons that take shields down fats. You should have each of each type, arc, solar, and void, for all different types of shields. For the jumping puzzle, if your hunter you should have stomped, if your titan you should use lion rampants. For the boss fight use celestial nighthawk and if there is a warlock, obviously use well. And or chaos reach. Also for the boss fight you have to kill everything which I think you know, so take care of the adds first. Use energy weapon Ex. Hard light to take care of the shanks. Use any regular kinetic weapon to take out dregs, marauders, vandals, etc. It is important that you attack the main boss last. The more adds you kill and the faster, the more damage you can do on the main boss at the end. Also you could use any fusion rifles, Ex. Sleeper, To kill some of the adds like the marauders that are really annoying. Also you could use any regular or linear fusion rifles to attack the spider tanks. Try to take out the adds quickly in the beginning to get good time. Hit the main boss headshot with celestial nighthawk gunslinger to do a whopping 618,000 damage! Ya when I took that first boss headshot my jaws dropped. Ok that’s all I have, hope you get the outbreak perfected.
