Don't think it's possible unless it's became bugged lately. I take it that you have the "Kill the Aetherex on the mountains" mission completed but Hayes still doesn't answer?
Do you have a "Note of recommendation" among the completed quests?
No I don't.
I did not get that mission as I recall.Next one after "Hunters for Hire" is "Jameson's Reach" from Corporal Mac Dillon, the guy who gave you "Hunters".
(According to entropedia)
Aha, that's it. For the Jameson's Reach NPCs to speak to you, you have to be sent there by the Corporal Mac Dillon (the guy at Naval Triton to whom you turned in the "Hunters for hire"), and for that you have to have completed A) Hunters for hire (you did it) and B) Note of recomendation and all those required missions up that chain.
I am fairly sure that I did all of the "Kill them all" missions. Is that the one where you kill traeskerons ?
BTW what do you get for the meat?
