For Colter in Fallout 4: Nuka-World , the weapon you need is the Thirst Zapper squirt gun to strip his shield, then a strong damage weapon to hit him while it’s down. The safest follow-up options are a high-damage gun like a Fat Man , Gatling Laser , or another powerful firearm.

Quick answer

  • Required utility weapon: Thirst Zapper.
  • Best follow-up weapons: Fat Man , Gatling Laser , or any strong ranged weapon.
  • Avoid: Melee or unarmed attacks while close, since Colter can punish you with electricity.

How it works

Colter’s shield has to be weakened first, and the game’s intended method is to use the Thirst Zapper on him until the shield flashes. Then switch to your real damage weapon and attack quickly before the shield comes back.

Extra tip

You can also defeat him with critical hits or V.A.T.S. in some cases, but the Thirst Zapper is the intended weapon and the most reliable route.
