An....interesting set, it is perhaps something of an unusual subject/theme to base a full set around, one that I must admit I'm at something of a loss to figure out how to factor it in to my campaign. As ever the graphic quality is excellent - I almost expect to see that rust rubbing off on my fingers!
I'm not sure how much use I will get out of it although the tiles to link this set to a regular dungeon were most welcome and definitely make it a lot easier a prospect to try and fit it in SOMEHOW.
Kudos to Ed for trying something unusual though! Perhaps some tiles with a little more 'detail' (I dunno, rusty machinery of some sort, rusted holes in the floor etc) would have been useful.
