Someone put a post up yesterday showing where to farm hadium, in the mausoleum at the far left (right at the bottom) there's a corridor that takes you to an area called the furns (or something similar) as soon as you see the location change to furns head back out to the mausoleum and there are 3 caves along the same wall, check in each of them (sometimes there are chests in more than one), then jump through the window of the crashed space ship (you'll see it hanging from the ceiling opposite the 3rd cave), there's usually a chest in there. Repeat and every other run you should get 2/3 chests (so long as you go far enough down the first corridor to see the location change). I got 25 hadium in about 30 minutes yesterday. Edit: here's the link to youtube to show the location (not my vid) [url=https://m.youtube.com/watch?feature=youtu.be&v=iE792R7lpEclink[/url]
