As it turns out, a PAU is making an appearance in patch 1.6, in unassembled form in a garage in Foreas Base. From what we can tell, it looks to be a Grendel, the Grenadier-class PAU that is one of the few to have actually been fleshed out by the devs so far. If you check out the video we've made of the new mechanized monster after the jump, two uniformed ladies appear to be conversing in front of the half-unpacked crate, but some sort of bug is speeding their dialog along at such a clip that all we can do is pick out random words like "coolant," "duct tape," and "human flesh." PAUs powered by human flesh? Confirmed.
