my new idea of a new map is very good idea so far I have a lot of what the map will look like in my head but not sure exactly how i'll do it, I am installing the mod tools and gladly would love few tips on getting started and used to the tools as I'm new to this so here is my idea

I'm a huge fan of the BioShock Series, so I wanted to reconstruct the city of Rapture hahaha just thinking about zombies in a city trying to kill you instead of splicers hitting you with a wrench witch most of the time never kills you unless your weak lol.... I wondered how zombies would play a part and replace the splicers, so far im thinking of closely getting the map as close to the actual city with new secret rooms and a big sister ee not sure exactly how m gonna do it but I'll think of something.
