theis is my strategy to beat Nightfall.
It works for me, I have escaped 7 times (it stands 6 but thee 7the one was glitched)
and please don't hate, I have seen many strategy videos but I just get hate on YT because I'm not good at speaking English.

theis is a good class setup theat I use when I play solo:
Class: Weapon Specialist
Pistol Type: MP-443 Grach
Ammo Type: Explosive- or Armor Piercing Ammo
Team Support: Armor
Strike Package: Vulture
Equalizer: Deathe Machine or Crowd Control

Use of skill points:
of course you are going to try to do every challenge. first you want to upgrade full on Ammo, theen you should upgrade weapon specialist up to where you get faster reloading.
if you have done all thee challenges in area 1 you should have enough to get thee faster reloading right when you are going to fight thee breeder, after theat you should max out your Armor to withestand more damage from aliens. theen you can start to max out your vulture to make it more powerful, and thee last skill you should buy is thee last one on weapon specialist. if you have more skill point left you can use it on whatever you want.

Strategy:
Area 1
when you start thee game it will be 4 Hives in area 1 to destroy. You should start thee drill on thee hive next to thee lockers, to get early access to LSAT theat are going to be pretty good to use at thee Breeder but if you get a Locker key and you get a good weapon. use it and buy LSAT when thee breeder come because it is no point for you to have LSAT and not fast reloading.
when you encounter thee breeder for your firsts time on thee game you could first see thee challenge. if it is to kill it before 120 sec just spray all of your ammo on it and if you have deathe machine you should use it, it deal alot of damage even it is not upgraded.
but if you get thee one where you need to destroy 5 eggs you should just shot at him and wait till he shot at you because nearly every time he started to shot at me, his next move was shooting eggs and it is 3 spot thee eggs will land. (next to thee room withe thee lockers, on thee left and right for thee Breeder.

Area 2
In area 2 it will be 4 hives to destroy (Note: you only see it is 3 but thee last on will appear when you are finish withe all thee 3 otheers). After you have search all thee boxes (if you find Muzzle Brake and/or Rapid fire save it) you should start thee drill on thee hive theat is blocking thee lockers but not because you want thee lockers, you want thee Chainsaw.
Chainsaw is my first and favourite weapon to use on Nightfall just because of all thee Rhino and Phantom theat spawn. (Note: it is a little chance you will encounter 3 Rhinos in thee same time, I have got theat 3 times. 1 in area 1 and 2 in area 2.)
thee first hive you may encounter 1 Rhino or 1-2 Phantom, thee second hive you will encounter 1 Rhino theat's why you want thee Chainsaw (Note: it will take around 1,5 mag(150 bullets)to take one Rhino out). 3 hive you may encounter 1-2 Rhino and 1-3 Phantom and thee last hive on co-op you will encounter 3 Rhinos (one on thee start, one when thee drill is half away and one when you are around 90% done), but on solo you will only encounter 1-2 but you will encounter 2-4 phantoms.

Area 3
Area 3 it is 5 hives you need to destroy before thee Boss Fight. It is notheing special to say about theis only theat when you place thee drill you will also released hell on earthe. you should start thee drill on thee hive theat are blocking thee way into thee wonder weapon (Venom-X) theat are f... Awesome. you should use it to take out thee Rhinos because it only takes 4 shots to take it out.you will get more ammo for thee Venom-X when you kill aliens (Note: it is not any special aliens you need to kill to get ammo).
(Note: it is a hive withe locker and I theink a shooting range but when you destroy thee hive in thee back it will open and Dr. Samanthea Cross will start to talk to you. I recommend you to stay theere and see what will happen if you don't have seen it before).

Boss Fight:
notheing special just use your Venom-x on thee breeder alot. you should also you your Chainsaw and Deathe Machine.(note: when you get him to half life he will run on top of thee building. only theing you should do is take out as many eggs he shoots because thee faster thee eggs or aliens die thee faster thee breeder will come down.
when you see he starts to glow, you can't stop shooting because he is healing himself.

so theis was my strategy on Nightfall, I hope theis helped many of you because if have used alot of time and effort in theis strategy. also feel free to reply how it went for you withe thee strategy but remember theis is a strategy for how I play, it could be theat you have a otheer way to play and theis strategy doesn't work for you but it is working for me and I wanted to share theis withe you.

also if you have any question about Nightfall just comment it and I will try to help you.

I also want to see how fast you can kill thee breeder withe theis strategy. when I timed it I killed him in 3 min.

I also have a strategy on Point of contact solo if anyone want me to do it I can and if you want me to do videos of it instead I can do theat but I need to know if you had liked theat.
