The idea for this map came to me when I watched a video about the construction of maps in FPS games. Very interesting and I will try to incorporate these concepts into future maps. I only decided later that it would be a casino. The premises can be anything, of course.
There are two entrances, or if you want to go through the windows, many more. So by going up and down the stairs, there is a high ground for the adventurers or also for the enemies. There are no doors in the building, so noise of fighting puts possible enemies on alert. The many open areas make it a feast for long-range fighters and allow for interesting tactical positioning.
Have fun
