Just pulled this off today. It was pretty close and involved a huge fight, but I managed to survive a fight with a horde with my NPC friend, who sadly did not survive due to faulty headware. Kind of sad, we were together a long time. We planned to loot a gun store and there was a horde right next door. Killed the, all.
So then I realized that there’s a hundred unpulped bodies in this room with me, the building is in sorry shape, and you know what’s right across the street, spawned in from gunfire? Yep, another horde.
So I said “fuck that” and torched the place. What ammo I couldn’t carry blew up, brought in the horde, and I just walked around on the far side as the walls came down and walked them through the fire. About 3 made it over to me and were promptly cut down.
So not 1 but 2 hordes were put down permanently here. Emptied the whole city, and it’s a pretty big city. So now I just need to fix my leg and I’m good as gold.
