This is a complicated level and I’m going to be using videos a lot more, because some parts are just way too confusing to describe in writing. Other than some very niche situations, there’s very little reason to use the other abilities. Grab the drop shield when you can, and use sprint otherwise. The Needle Rifle is just as efficient except you need to aim a whole lot less. Note that the DMR tends to take 1-2 headshots to pop their helmet off, and 1 more headshot to kill. Since they’re mostly unshielded, you can kill one with 6 Needler rounds or three body shots with the Needle Rifle.
That means all of Exodus, the hospital in New Alexandria, and the final wave defense segment in Pillar of Autumn.
Brutes are hilariously weak, and you should consider replacing the Plasma Pistol with the Needler and the DMR with the Needle Rifle on areas where they’re the dominant enemy. You can almost always take out most of the enemies from a safe distance with your precision weapons. More times than not, there’s no reason to push in. Optimally, this means that you’ll be using 1-2 rounds on Grunts and 2 rounds on Jackals. Always aim for the exposed hand on the left of a Jackal shield, then tap them on the head while they’re reeling. Tap grunts on the head once or twice and they die. Use headshot weapons for all the normal infantry. If you don’t use this combo, you’ll be wasting ammo and time on Elites, both of which are valuable on legendary. Whenever you encounter an Elite, dip behind the nearest cover, charge your Plasma Pistol, pop out and shoot them, then quickly switch to your headshot weapon and tap them once on the head. That means a DMR, Needle rifle, Magnum, or hell, a Sniper Rifle. And always carry a weapon capable of an instant headshot kill in your other slot. There’s no reason not to, and you’ll just be making things harder for yourself by not doing it. Always carry a Plasma Pistol unless I specify otherwise. On missions where you have Noble team allies, always let them push up in front of you and grab most of the attention.
