If you havnt done it yet, i will be getting that mission very soon (unless i grind some lvls in the Hollows) so if you still need it PM me to let me know & i'll count you in Np.
Im sorry if you havnt done it yet but we went ahead and completed the splunka yesterday night, sorry.
If you are still without it, contact me at @hammerfall, and ask about spelunker 
. I have a lvl 13 alt with the mission, and so far none of my friends havent needed it so..
I dont know when I will be online though, early evenings propably (I live at +2 hour timezone)
Well, Madame Curie did get it with help of SG mate. Thanks for all the answers.

My dear GF's toon, Madame Curie, need Spelunker badge for her first EVER Atlas Medallion. I've tried to make her understand the wonders of Badges and Accolades but she just says:"But the game is fun anyway." So I figured I'll get one of her toons an Accolade and get her hooked....
So, if anyone have it I'd like to join. I'll be online with that toon tonight after 21:00 CET (20:00 BST). =)
Will of course, check the forum first to see if anyone with that mish is kind enough to let a Lvl 28 Rad/rad join.
