I started building a model of my RL house to use as a base for my campaign. I'm starting out by building the basic structure from foamcore board. After a lot of internal debate I decided to not try to do the interior. I figured it would take way too long and keep me from continuing my campaign. As the good people at THW say, 'just play the game!' I'll use the I, Zombie building rules for any fighting that takes place indoors.
There are two dormer windows on the front slope of the roof. These will give great roof access and I'm thinking of building a catwalk around the roof as part of the defenses. We'll see how that turns out!
It has been great to imagine my home in a zombie apocalypse and then to plan how I would fortify it. A fun project so far and only just getting started!
