So I'm like whatever, I start walking around collecting all the junk, and every two seconds I hear them up there, talking, saying they hear something... Yea, you heard one explosion and several gun shots! Come get me! But no, they just stay up there talking as I'm running around collecting the loot. Say what you will about Skyrim's enemy AI, but at least they actually made an effort to run to wherever they hears noise. These raiders are eithet extremely high off of their jet, or there is no way for them to nagivate to the lower level. Not just that, but the 'warning' detection turns back to normal way too early, no investigating.
Anyways, love this game, it was just annoying listening to them talking as I was running below them.
