It’s been a bit since I’ve posted so I thought I’d give a small update on my progress. I’m currently still working toward the playable grey box prototype. I’m getting closer and closer each day but i still have a bit to go.  So far I have a basic city building at run-time with roads that interconnect and houses running alongside the roads.  I have graveyards that spit out an endless supply of zombies, and I have a very basic AI in place that knows how to infest new buildings and how to chase after that pesky player character if he/she gets too close/ within eyesight of any of the zombies. So some progress but much still to accomplish. Anyway, here enjoy some screens.
