SteamPoweredTV gives us a look Boom and Zoom, which they found out about at SoCal Smackdown.
From the update:
This is essentially “part 2” of my exhibitor’s hall walk-around. Here we’re looking at one game in particular, and that’s BOOM AND ZOOM. It was pitched to me as, “Checkers with guns” and being a wargamer they had me the second I heard the phrase “with guns.”
