Open Season

Open Season is a quest in the Fallout 4 add-on Nuka-World.

Quick walkthrough
After getting the quest from Mackenzie Bridgeman or Preston Garvey or through murdering Porter Gage, the Sole Survivor must go to the gang leaders locations and execute them, Nisha will be in Fizztop Mountain, Mags & William will be in The Parlor, and Mason will be in Bradberton Amphitheater. The player can execute them in any order but once one of the leaders is killed, all the raiders in the park will become hostile to the player.

After all the leaders are dead the player could also kill all the attacking raiders to avoid any disturbance when talking to Mackenzie, after speaking to Mackenzie then the quest will be completed.

Bugs

 * If completed before starting any quests given by Porter Gage, he will stand idle on top in the overboss's room, and will not provide any dialogue unless engaging him in combat.
 * After completing the quest, leaving Nuka-World, and then coming back, all of the traders will unequip all of their inventory items, including any clothing, instead of only their explosive collar. It is still possible to trade with them.
