How to beat the Final Boss (spoilers)

I struggled alot with the final boss until I finally figured out the mechanics and guessing spawns alot so hopefully this guide will help you out. This is the very last mission to beat the game. Spoilers obviously.

General

So the final boss fight has 3 stages which I will call Normal, Green, and Red.

Each stage doesn't get progressively harder it just uses new mechanics.

This bossfight honestly just tests your memory and reaction speed.

The enemy spawns will always be the same and isn't randomized so you just have to memorize where they come from. I took alot of trial and error so you don't have to.

You have infinite ammo and don't have to reload except to chamber and load the next round.

You will start the mission overlooking a city with skyscrapers, parking lots, etc around you. You will be in a confined area. Picking up the sniper will start the bossfight.

Stage 1: Normal

The first stage is normal which is the easiest part of the boss fight. The boss will spawn from a green portal with a loud noise. Remember! The spawn doesn't change so you can pre-aim that area.

Here is where the enemy will spawn.

Rooftop of building in front:

Behind the billboard in the front:

In the courtyard on the right side: I would move over to get a better shot.

After shooting him the screen will have static and then move onto the next stage.

Stage 2: Green

In this stage the surroundings will now be green. The boss will fly at you now and you have to shoot the one thats not transparent. Lucky for you reading this guide I already did all the trial and error so I can show you were the real boss spawns.

The transparent enemy when you look at them are see through and there's no point in shooting them. They will fly at you and do nothing.

The non-transparent enemy will actually damage or kill you. In this stage you have 2 hits until you're dead. The first hit will cause some claw marks on screen and the second will kill you. Dying will restart the entire bossfight from the beginning.

With that out of the way here are the spawns: *the arrows indicate from where he starts and will move to*

Looking at the front, left side between the buildings:

Look up and he will fly down into the center and then at you:

From the right side of the screen from above again:

Shooting the real boss 3 times will once again trigger static and move you to the final stage.

Stage 3: Red

This is the final stage of the bossfight and honestly really easy once you know where the damage spawns are. In this stage the boss will be giant and will rip off the roof of the building your in. That doesn't do anything so don't worry about it. Ignore the big boss, shooting him does nothing. After ripping off the roof the boss will start raising its hand.

If that hand hits you, you are dead and have to restart the entire thing again. it doesn't matter if you took no damage so far. The boss will repeatedly raise its hand to hit your building and you will be looking for a green light with a enemy spazzing out that you have to shoot.

Anyway here are the spawns: circled

In the front under the boss, in the apartment building:

Right building at the door entrance:

Parking lot left side:

Balcony of the right side, you have to actually move and look to the left:

Inside the water tower, in the front

With that done you have beaten the boss, congrats!

You did it!

Congrats you beat the game!

@Mudskipper You would be surprised how many people complained saying this fight is almost impossible! Something that requires a little bit of patience is more than enough to make people mad nowadays.

An extremely easy boss fight why did you make a guide

@CaptainCobana I finally unlocked that Basement achievement by killing the only witness that sit on ledge of small stairs before you go inside the factory which full of security guards. Then, survive the basement of factory without death

[CaptainCobana]

I got them on a fresh playthrough on my Steam Deck (as opposed to my PC). It was probably Just the fresh save file but anyway. Didn't need to do the final portion for that.

@CaptainCobana @Coloneljoe20 I haven't gotten the achievement either and honestly I'm not going to I didn't like this games final few chapters and ending at all.

[CaptainCobana]

@Coloneljoe20: Unrelated but you're not the only one. Same here. Also didn't get the achievement for all the evidence.

One question. How to get Basement dweller achievement? I already beat that section without die or got violated by psychos in that basement under factory
