that's some top work on these figures. I took the easy way out and ordered a bunch of heroclix figures for all the civilian workers and security guards that I rebased and did small paint touch-ups to for my set, all that plastic is still in the box mostly untouched. The amount of stuff you've got completed is impressive. I keep intending to break them out and paint up the other MERCS teams at least, now that the regular miniatures game 2.0 rules and cards are a free download on the website. One day.
I agree the game is good, I was surprised to get a full kickstarter set off ebay for much less than the cost of the KS. A lot of backers were disappointed with the final product, but I think it's great. Haven't played it multiplayer, but it's a good solo game and Boardgamegeek has some files to make it easier for solo play like smaller character boards to track an entire team at once. You can do it with the regular boards, but it takes a lot of space.
