Forgot what they were called but went to go shoot at the stupid things and they dominated me! I spent like ten trys to get past 4 of them! I love the challenge but every time i see these things I run haha

Bloatflies?

Yeah, I know what you're talking about. Man, first time i saw those I'm like "Ah, cool another flying creature. probably about as tough as a bloatfly..." ...and then I was dead in one hit.

No, http://fallout.wikia.com/wiki/Cazador. They don't have much health, but damn do they do a lot of damage. And they're fast too. If you can cripple their wings, they're stuck walking like the rest of us. Much easier to take on that way.

Can't be bloatflies, I was playing for a bit and took 4 of them out before they even saw me with the tutorial rifle. They are even easier to target and kill than they were in FO3.
