Story related so can't be missed.

SOME TIPS (with possible spoilers):

-Use the cover in the middle of the middle platform against the final boss.
-The eyes and middle of the chest are the weak points.
-Save your heavy weapon ammo for the Harbringer(s) and final boss.
-Move around to collect ammo when you get low, and try to stay under cover as much as possible.

I personally just used my sniper (I upgraded 5 times and had the Geth model) on a majority of the enemies because it was a one shot, one kill deal. I used the AR only when I ran out of sniper ammo. The best heavy weapon to use imo is the beam rifle (the Collector weapon) because there's no down time for reloading.

Remember that it's not timed. Don't expose yourself when it's dangerous. Your squad members can kill the collectors that come during the battle. Also, save your heavy weapons ammo. But the most important thing is taking your time. If the boss is charging up his main crazy gun thing stay in cover. That weapon will kill you.

before the final battle make sure you have a cain and all ammo upgrades for it. if you do 2 shots from it will kill the final boss just be careful and don't miss. But if you do miss don't worry the heavy pistol does a decent amount of damage to the final boss. sniper rifles also work good.

note the 2 shots on regular will kill it i haven't tried it on a higher difficulty but I would assume it takes more than 2 shots with the cain.
