Raven Creek is a very well put together mod that adds an entire city and surrounding residential areas in the SW corner of the map, I want to say it’s larger than LV. Lots of verticality, multi-story apartments, condos, office buildings, stores, etc. complete with a shipping port full of containers (with goodies inside), underground bunkers/tunnels, a large FEMA camp, a penitentiary, and an extra smaller island town to the south. Oh, and the entire thing is fenced in, complete with checkpoints but there’s really only one main way in/out that’s heavily fortified and VERY busy. The fight out the main checkpoint is easily one of the highlights of my Zomboid playtime. There are so many little hidden features and details, I think it’s become my favorite mod to date. The mod creators just put so much effort into it and it shows. I literally can’t say enough good things about it.
I will warn you though, sometimes the spawns screw you and you spawn on the roof of a 10 story apartment building that has locked doors and is completely full of zombies. Can be a major source of frustration, but it all adds to the experience, just trying to grasp a foothold and carve out space in somewhere completely overrun. Highly recommended!
