My first run-in with the Cazadors was at a raider camp. I was up on a mountain and looked down, and saw a flock of those bastards, didn't know what they were but there were dead bodies everywhere so I knew it couldn't be good. So I circumnavigated the camp and went on my way, somewhere along the way I died, restarted and came across the same camp with no Cazadors, so I investigated; I went to sleep (autosave) and when I woke up there where at least 5 Cazadors surrounding me! I tried several times to get out of it legally, but was slaughtered every time, so I finally had to console-TCL my way out of it. Funny thing is - even after escaping them that way, no matter how far I ran, they seemed to be tracking me, even when the sneak indicator said I was clear! I finally had to fast-travel across the map to finally get rid of the problem.
Heyyy, you were at Tribal Camp! :tops: That happened to me, too. I randomly decided to drop everything at level 8 and head for Vegas, and get in there no matter what. So I traveled north from Goodsprings and the Cazadores started schooling me on how to die really fast. So I started over from Goodsprings, kept left, and kind of glitched/climbed along the invisible walls to avoid them. Anyhoo, I came across that same camp, with around 4 Cazadores and 2 Young Cazadores swarming around a bunch of dead bodies, but I was on a ledge way above it. Went into sneak and it said [DANGER] so I knew they detected me, but they couldn't reach me for some reason. (Even though they can fly? Okay...) Couldn't reach them in VATS so I shot in first person view. (I could have just dropped down and gone for it, but I'd come pretty far and I planned on getting to the Vegas strip and running around without saving at all...)
Was really high up, so it was hard to aim accurately, and a lot of the time they were behind a stupid tent. I tried all the guns in my inventory, I had Varmint Rifle, Single Shotgun, Lazer Rifle, even a Sniper Rifle, etc. Later on I also fought a whole swarm on the ground, and it was
not that difficult after I learned that.....
TL;DR: The guns that worked the best (and by the best I mean from as far away as I was, would kill one in 2 or 3 hits), was the 10mm Pistol or 10mm SMG. Regular bullets worked fine, but HP packed extra punch. That's what I love about Fallout, the experimenting!!
