Assault scenario

This scenario is very particular about location.

First of all, you should have an object of assault on your location, preferably in the center of it. Best of all would be to have a multi-story building, but it can also be a one-story building or some height or forest block.

What is most important that it should have a certain set of shelters, and players should have the ability to get close to and go into it from several directions.
