To spawn Mercenaries in EFP, you need to get a letter that you give to Otacustes inside the camp. (Otacustes is himself spawned randomly by killing over and over the Primus mob in a corner, until Ota swpans instead of a Primus.)
To get the letter, you need to talmk to the ICC Commander who is walking around in ICC.
The Commander tells you about the location of Joe Two-Fingers; this can be several spots in Andromeda.
All this is explained in AO-Universe, to which usually people refer.
But I discovered a while ago, and "rediscovered" today, while getting a letter for our newt Mercenaries raid Friday, that there is a spot NOT listed by AO-Universe:
If the ICC Commander says:
ICC Peacekeeper Commander: I heard he was measuring some crops at a farm quite far west of here earlier today. Maybe you'll find him around there.
Then you must fly to the West of ICC HQ, to a village marked "Terra" on the map, full West of Andromeda and Joe will be in a crop field near the village.
Pos: 848.5, 751.3, 4.1, Area: Terra.
