This is a screenshot of one of the mines that appears in the beginning. Apparently they're called Bomas and Carmine and appear at the start of RuptureFarms, one each in Paramonia and Scrabania, and then one last time together in The Boardroom. The blue one gets stuck at the start of RuptureFarms and I've gone through Scrabania and Paramonia too many times searching for these two "characters" but here's some screenshots with the gamma up so it's clearer to see.
E:Getting that Boardroom one was hell, I hope they fix the timing on meat saws/bone drills and UXB bombs in Soulstorm, and why Abe falls on his face in the Boardroom between the two sligs leaving basically no time to activate Shrykull before getting shot I have no idea.
