Wow... what a fantastic map!
This one is huge, and covers a wide variety of buildings - don't be put off by the fact that it's a naval base, it's got a hospital, cinema, gym, nightclub, barber shop, laundry, dental clinic, classrooms, warehouses, various shops and diners, workshops, offices and even a chapel !
It's an entire community.
Each building is mapped separately, and highly detailed - even down to where the power supply comes into the building, along with NPC's you'd expect to see and workers shift patterns for each building.
This one product gives you a large selection of ready made buildings to drop into any modern/post-apocalyptic game, and comes with plenty of hints at possible scenarios to link everything together.
Worth getting if you need maps of buildings, even if you don't need a full naval base.
NOTE - the key on the overview map is reversed ! If you read it as 'A' as the rightmost column and 'o' as the left, then each building description has a grid ref to locate its silhouette, however the reverse is not true - there is no easy way to look at the map and work out 'what is this building?'
