The Evil Within

This is story related... i had some trouble with it, so i found this video on youtube. Credits go to markmonster. Be sure to upvote his video on youtube.

Just want to add a few tips myself here -

The most common strategy for this boss is to hide behind the first pillar you get to at the start of the fight, and then snipe his eye until he starts the second phase of the fight.

Phase One tips:

If you don't intend to do the sniping strategy then a good move that you can do at the start of the fight is hit him with a flash bolt, ie the one that stuns, not the one that electrocutes. Aim at the base of his rib cage sticking out in the back, and he will fall to the ground if you hit him just right. This allows you to run up to him, and unload on him.

You can actually shot of his heads at this point, and it seems to do quite a bit of damage. He has the two monster heads in the front, and then I think he has one human body with a head on top and bottom.

Caution! - Once he gets back up you basically will have to go straight to a second stage strategy as he will obviously know where you are. Also beware, after the first stun bolt, the weapon has zero effect on him. Ie once you stun him once, the flash bolt will not work again, and it won't even stun him. Its a one time use.

Moving on to sniping......

The first obvious pointer is that it takes 2-3 shots on casual, 3-4 on survivor, and 4-5 on Akumu assuming you have no upgrades to damage. I have seen a video with a fully upgraded sniper rifle getting him to phase 2 in 2-3 shots on Akumu.

Generic tips you can find in most videos:

1. hit the eye, not the "lashes"
2. shot once and then hide again, don't try to get multiple hits on him, he will usually spot you
3. you can hide behind cars as well, but if he gets too close he swings his eye over the car and sees you, with pillars he can't see you but you have to be positioned correctly, ie on the first pillar you have to move with him and make sure the pillar is always between you and him
4. I don't know if this is generic because most people don't suck as much as me at sniping, but you can miss and stay hidden, in one fight I literally missed him 5 times and he did not find me
5. If you have green gels, max snipe damage and/or critical shots. The sniper can be usefully on most boss fights so its not like you waste the gels only on this fight, the down side is that most bosses are kind of hard to snipe due to the zooming.

My own observations:
1. he has a pattern that he does, of his various movements, I find one instance by far the easiest for even the poorest sniper, he will change between having his eye up high when scanning, and having it low. The low angle is actually the best, but only when his back is turned to you and facing the small room at the beginning of the stage. This is the one position where he never really turns in the direction of the pillar. Its a little hard to shot because his body blocks have of his movements, but there is plenty of time when he swings his eye to the right for you to shot. This will be a slow part of the fight because he only gets into this position once every 3-4 minutes, but be patient.

Below I will link TheSeraphim17 ch 10 akumu w no upgrades video, fast forward to 6:12 in the video to see the position I am talking about (Seraphim mentions it being an awkward loop). Due to him scanning with his eye low, there is no chance of him swinging it around suddenly like when its up high, and he has a much more limited view both in terms of range and scope. The main benefit of this angle is that you can come out much further from the pillar making an easier shot, and also have a lot more time because you don't have to worry about a sudden swing.

2. Even if he spots you and breaks your pillar, you can recover and snipe again. You have to run out of his line of sight, and the hide behind another pillar and you can go back to the pattern. I find the pillar blocked with a car at the end of the "hallway" to be the second best spot. The SUV gives you extra cover in addition to the pillar. Then there is one more pillar in the first part of the room, and I think two more in the back.

Contrary to the above video don't go into the rooms at anything above casual difficulty. You just don't do enough damage to him in the first phase on the higher difficulties so you end up wasting valuable high damage ammo just to get him to phase two, and handgun ammo won't cut it in phase 2 on higher difficulties.

Although, you can snipe from the rooms as well and stay hidden, but I find these to be particularly hard to snipe from and he can detect you a lot more easily.

One interesting thing about his movements if he spots you, he does not charge right away, so if you just start trying to strafe him right when he spots you, you will get hit. What he does is this jump back to line you up and then charges you. So wait until he starts the charge to try to strafe, back up until then.


Phase 2:

1. You need Freeze and or Electric Arrows. Once he changes color, there will be a orangish pink section on his body kind of like RE telling you aim there. In particular the eye. You need to freeze or electrocute when the pink area is facing you. Switch to either sniper, grenade, or explosive bolt and aim for the eye while he is frozen. If you don't you have these or run out go for the shotgun, and I guess worst case scenario handgun.

2. When the eye gets hit, he will normally go down for a few seconds allowing you some precious time to either wail on him some more or get distance.

3. The main thing that I want to caution you on is that he has an instant kill. Even on survivor his damage is so so, the main thing that usually gets you killed is when he corners you, but you can take quite a few hits. But in phase 2, if he rushes you, and you are directly in front of the pink area, he will eat you and kill you instantly. So be careful even if you are using freeze and electric bolts, if he does not go down with your damage, you will basically charge directly into you usually starting the instant kill.

Also make sure to watch the entirety of TheSeraphim17 video because its really good. Just use the angle mentioned if you are having difficulty sniping him normally.
