The 31st Well[]
As of this moment the map only lists 30/31 wells, but I think I just found the missing marker. While using this map (and only two wells in) I noticed that the wells in the in-game map can be seen as very distinct small black circles. I then scoured the map in the top right and found on such cricle in the palace grounds. I went to check there and, sure enough, there was a well. For me it was uncovered, but that's probably just because I came across it during the missions revolving around infiltrating that area. After all, I was already in the habit of blasting them on sight at that point. Merik2013 16:09, June 23, 2012 (UTC)
Still hunting them down and just found another unmarked one (probably the one we're actually looking for) next to a bomb crafting station above and to the north-east of the Arsenal. It's not all that far from one of the other wells. Merik2013 17:12, June 23, 2012 (UTC)
Just finished going over the map and I can now see how people are getting stuck at 27/31, as I am now. The map only shows 30 nodes and of those 3 of them weren't covered to begin with. Niether of the two I found helped get me any further along either. No idea what to do here. Merik2013 17:12, June 23, 2012 (UTC)
