It was the zombie apocalypse again. Human survivors were scattered around. It wasn’t so sparse as in many zombie apocalypse stories, but the zombies still had the upper hand and survivors lived in fear.
I and some others lived in the top floor office of a massive warehouse/factory type complex. It was handy because we could monitor the floor below from the office window. Zombies would get in and wander their way near us. They could be taken out without alerting zombies outside, because it was indoors, but there was enough clearance room to have ample warning and reduce risk. It was a pretty good situation.
