Evil West has accumulated four main boss fights sprinkled all across the 16 main missions through which the player has to progress to complete the game. The boss fights can get exceptionally challenging at times. Therefore, my Evil West All Bosses guide will uncover all of them in detail and work out how to defeat them!

  • The main benefit of defeating these bosses is that you will be one step closer to getting to the end of the game!
  • While bosses can get insanely annoying, practicing patience and calmness during the fight is crucial to succeeding!

The Parasiter 

Kicking things off with the first boss in the game, the Parasiter is introduced in chapter 7, which really spikes up the difficulty level all that much. The parasiter is one of the few challenging bosses that require strategy and stealth from the player’s end. 

First Phase

  • For the first phase, focus on the left tentacle’s weak point marked by a golden circle.
  • Shoot it, roll forward, and initiate 2-3 melee attacks before it rises.
  • Repeat the process, evading right tentacle attacks.
  • After a stabbing attack, perform more melee hits on the right tentacle, shooting its weak point.
  • Run to the other side to avoid poison and execute melee attacks on the right tentacle during its stabbing sequence.
  • Once both tentacles are down, shoot the vulnerable points on the leech to proceed.

Following through with the next boss, you have The Bruch, which will be introduced to you when you end up reaching chapter 10 of the main questline. As for the overall difficulty, the boresight will be on the easier end compared to the parasiter. 

First Phase

  • Prioritize eliminating these foes while adeptly dodging the fireballs hurled by Bruch.
  • Look upward to identify his vulnerable points, then use your rifle to target and shoot them.
  • Bruch will persist in deploying tail attacks and spawning enemies until approximately one-third of its health remains.
  • Remain focused and efficient in dispatching both enemies and exploiting vulnerabilities.

Third Phase 

  • When the boss has about 1/3rd health remaining, long walls of enemies spawn, rotating in a line.
  • A small gap opens for the player to navigate; being attacked heals the boss.
  • The wall repeats without rotation, launching toward the player.
  • The boss shoots fire projectiles but reveals weak points.
  • After hitting the weak points, the boss becomes vulnerable to close combat.

William Rentier

As for the next boss fight, payers will encounter William Rentier when they manage to reach level 14 in the game. When it comes to the overall difficulty, the boss is equally tough, but it’s nothing players can’t defeat with a bit of strategy up their sleeve. 

First Phase

The boss fight will start once Jesse can find Felicity, and Jesse will end up being furious about the fate of his father, and the interaction seems pretty standard with Felicity, but once the fight starts, her true form appears.
