How to unlock the The Castellan Falls achievement in Resident Evil 4 - Definitive Guide
This is a storyline related trophy and cannot be missed. At the end of Chapter 4-4 you'll be racing up a tower to confront Salazar, once you make it to the top you'll see a Merchant a Typewriter and a doorway leading to Salazar. Defeat the hideously changed Salazar to earn this trophy.
Salazar is the trickiest boss fight in the game and has a lot going on at once.
Tentacles
Before we go on understand how this room is, you're on an elevated platform with two tentacles (one on each side) and Salazar's tentacle in the middle. Run to one of the sides of the room (I prefer the right side) to avoid Salazar's tentacle attack. If you are in the middle of the room he will do an unavoidable instant-kill attack. The tentacles will continuously attack you but every attack can be dodged with a contextual command. If the tentacle is too much for you to handle you can shoot it and it'll withdraw for a while.
Fight
Look at Salazar's tentacle, that huge yellow eye is its weak spot. You will need to shoot it to open up Salazar's actual weak point. You'll know when you shot the tentacle if your attack releases a yellowish splash. After damaging the tentacle enough it'll keel over in pain and Salazar's weak point will open up (he's atop the middle tentacle). Attack Salazar until his protection covers him again. Now repeat shooting the tentacles eye and then attacking Salazar directly until he dies.
Other
If you run low on ammunition you can drop down to the lower area. Salazar cannot attack you there, however there are infinitely spawning Las Plagas down there.
This is story related and cannot be missed.
Just like some of the bosses, there are two ways you can deal with it.
Near the end of chapter 4-4, you will need to defeat Salazar.
1: If you can get a fully powered Broken Butterfly. Shoot the eye until Salazar appears it should take one shot with the Butterfly.
Now shoot him as many times as you can with the Broken Butterfly. You may have to repeat it twice as he takes up to nine shots for him to die. You may have to dodge the tentacles from the left and right. When the monster starts opening its mouth run to the left or right, so it does not eat you.
2: If you have the cash and the space to carry one you can buy a rocket launcher from the shop before the battle. You will still need to shoot the eye to make Salazar appear then hit him with the rocket.
RPG one shot.
Strategy - We shoot something in the eye, preferably from a mortar, after several shots, depending on the difficulty of the game, when the mouth opens, when it wants to swallow you, it is best to jump down, there he will not reach you, Salazar will open, we shoot orders at him 10 hits from a magnum and he’s dead.
