Perhaps it's a war zone, or there was a riot here. If your game is post-apocalyptic, whatever caused the apocalypse has damaged the area and caused it to become abandoned. Whatever, and you can come up with a multiplicity of reasons about why this is a derelict and ruined area, when you have need of such a site to explore and perhaps fight over, well, here you are.
Centred around a ruined building - the cover picture suggests that it is multi-storied although the top-down nature of the plans themselves gives little indication beyond a staircase - most of the plan shows an open area with a couple of wrecked cars which might provide cover although they are long past looting for spare parts, never mind trying to get them to run! There is a lot of debris on the ground both inside and outside the structure, giving the impression of a place that has been abandoned for quite some time.
As usual, you are provided with full-colour top-down views in multipage and single large sheet versions, with the option of a square grid, hex grid or no grid at all. The gridlines are unobtrusive: they are there if you look for them, but do not detract from the overall appearance of the scene.
You may find a use for this in any contemporary or near-future game - not necessarily a war-torn or post-apocalypic setting - or even further into the future (although it may be difficult to explain away the cars, but they are not so recognisably that, it would be possible to say they are the wreckage of something else - personal shuttles, perhaps?). One worth having to hand.
