Complete walkthrough for Part 21 of Gears of War 4, featuring the challenging Corpser boss fight and strategies for Insane difficulty.

Walkthrough
  1. 1
    The chapter begins with a fight against an Angry Titan (A36).
  2. 2
    The main event is a boss fight against the Corpser.
  3. 3
    After defeating the Corpser, proceed through the area towards where Cole and Baird appeared.
  4. 4
    The path will seal behind you, leading to a checkpoint and the next chapter.
  5. 5
    The end of Act 3 is approaching, with a segment involving Theron Guards.
  6. 6
    As you proceed, you will find the Torque Bow. It is advised to pick it up if it's your first playthrough.
  7. 7
    Marcus tells Dom, Cole, and Baird that he and Dom will go into the pumping station while Cole and Baird flank right.
  8. 8
    It is advised to take the right path instead of heading straight into the pumping station.
  9. 9
    Keep walking down the right path until Dom asks, "Do you hear that? What the hell's that sound?"
  10. 10
    Take cover at a chipped L-shaped wall and use the Longshot to snipe enemies when Marcus says, "Let's clear that station!" This is easier than the direct path.
  11. 11
    If it's your first time on Casual, the left path is an option.
  12. 12
    If you don't have the Longshot, you'll need to get on the platform and pray.
  13. 13
    Once enemies stop coming, head towards where Cole and Baird likely are and go up the ramp.
  14. 14
    Slowly make your way around the platform, killing all enemies.
  15. 15
    Head down the ramp and keep going straight.
  16. 16
    Look for a green button on the right and press it.
  17. 17
    Two more Acts remain.
  18. 18
    Act 4 (A4) begins with the Ashes Overview (A41), where the objective is to go to Marcus's house.
  19. 19
    Theron Guards are prevalent in this chapter and are easier but still dangerous.
  20. 20
    The chapter includes a Berserker fight before reaching Marcus's house.

Boss Fight: Corpser

  • This is considered the easiest battle in the game.
  • Memorize the strategy before attempting.
  • On Insane, act quickly to prevent Wretches from appearing.
  • The Corpser tries to crush you by stomping with the leg nearest you.
  • Stand by a leg, wait for it to raise, then run.
  • Shoot its stomach.
  • It will scream and raise its head; shoot its neck.
  • Repeat this three times.
  • The Corpser will back up onto a platform.
  • Shoot the two hedges on each side of the platform to break them.
  • The Corpser falls into the Immulsion, completing the task.
  • On Hardcore or Insane, you will earn an Achievement.

Insane Notes:

  • Beat the Corpser fight quickly or don't bother.
  • The Longshot is crucial for the segment after the Corpser fight. Without it, you must go directly in and meticulously pick off enemies.
  • Theron Guards are a new threat with accurate Torque Bows that can kill in one shot.
  • If you hear a Torque Bow charging or see its sight lights, stay in cover.
Tips
  • The Torque Bow is available but not recommended for single-player unless it's your first playthrough.
  • Taking the right path instead of the direct pumping station entrance is advised for an easier approach, especially on harder difficulties.
  • The Longshot is essential for the segment after the Corpser fight.
  • Achievement for defeating the Corpser on Hardcore or Insane.
