Show No Mercy

Show No Mercy is a quest in Fallout 4.

Quick walkthrough

 * Meet with Elder Maxson
 * Kill the Super Mutant Behemoth (You're in a vertibird circling it with a minigun)
 * Secure Fort Strong
 * Secure Fort Strong Armory
 * Speak to Danse
 * Speak to Arthur Maxson

Quest stages

 * Elder Maxson has ordered me to head out to nearby Fort Strong and cleanse it of all hostile super mutant forces. There's a vertibird standing by on the Prydwen's Flight Deck that will fly me to the location.


 * I've exterminated all Super Mutant forces at Fort Strong. I should link [sic] speak to Paladin Danse before I head back to the Prydwen.


 * Paladin Danse has ordered me to return to the Prydwen to speak with Elder Maxson.


 * Elder Maxson was pleased with my work at Fort Strong and has provided me with Vertibird Signal Grenades to call in a vertibird if I need it for travel.

Bugs

 * After getting the quest and talking with Elder Maxson the marked Vertibird to take you Fort Strong doesn't work. You may need to take the Vertibird on the opposite site down to the ground underneath and back to hopefully be able to use the marked one.

Another bug happens when the player has cleared out the Fort Strong Armory. The next objective is to speak to Paladin Danse. When the player engages Paladin Danse, he immediately attacks. He will take no damage. If the player fast travels to the BOS Airship, the BOS will also attack the player instantly. No clue why this happens. It makes this game frustrating.
