ok I have it and have played it with bots. It fundementaly sound. A few things to look at.
1) you have a ufo in behind the market building and in front on the apartments not sure what it is.
2) The doors do not seal all the way so you can see into the building
3) I like the way you put the trap door on the roof, but no one would build anything like that. I suggest you change it to a metal trap door, or even better make it a vent of some sort that you have to crouch to get into and have grates you shoot out to get into the building.
4) Loose the crates on the roof, there is no need for them and there is no way that anyone in real life would put them up there. Haveing something up there is cool though so you can snipe from cover. Maybe a huge sign?
5) If you get right up against the wall you will stick out through it. Thus you are clearly visable from outside. While this is great for stopping campers, it sux if you are trying to sneak up on them.
6) This is just a suggestion. You have that very cool center garden/monument area. I think it would be supper cool if you had like a tunnel or somthing from there under the building. Make it like an air conditioning shaft or somthing, even a city sewar access.
Other than that good job.
