I am amazed there still is not much of anything posted about the rest
of stuff that came with the KS.
How are satisfied with it generally?
Does it add a lot to the game?
Are new MERCS faction interesting and different (I am mostly interested about stuff that came in the core Agent pledge)?
Also: does the KS pledge pack contain some of the MERCS level backers custom figures?
What about "House 12 Saint" figure and mission?
The custom figures were not sent out to backers. I don't think the reason why has ever really been explained as at least some of MERCS level backers definitely said during the campaign that they wanted to share their figures with other backers.
And yes, the house 12 saint was sent out. The only things that were never sent to backers were player boards for the stretch goal mercs, sniper rules, mercs level custom figures, and four of the eight cardboard doors.
