Let me just express how incredible stupid that type of scripted attack is (out in the middle of nowhere with line of sight in all direction and BOOM, 4 guys out of nowhere), but to also have the level of difficulty suddenly jump 117 degrees is just meh.... And I have just been playing FO3 with the Wanders mod, and New Vegas on hardcoe, Very Hard, Melee, is surprisingly easy in comparison. Easy, except when the game suddenly throws an impossible challenge...
So, do I reload an earlier version and NOT kill the guys in Nipton? That is just horrible game play, but perhaps that is the only choice...?
(And don't suggest fighting them: I can't not melee even 1 of them, I can not dynamite them, I can not lure them to the NCR outpost.)
