Thanks. Thankfully, I was the muncher not the munchee, so I had a great time.
There are four 'boards' there: two 24" x 24" and two 12" x 24". They can be configured in different ways to maximize replayability. Plus, I've got a bunch of resin scenics on plexi bases for scatter terrain to break up any long fire/travel lanes. More 'Underground Lab' than 'Hi Tech Space ship' but they make for a decent gun crawl.
