Just download the PZ Dedicated Server files, and set it up locally. It's what I do, and I'm having a blast!

Even comes with the benefits of fine-tuning and tailoring it to your own personal preferences, so if there's something you want to add, remove, edit, it's free game!

For instance, I also added the Basements mod, so now I have the added benefit of not only decorating my base in-between rounds, I also have the option to EXPAND it to store even more loot and stuff! Also got the Game Systems mod, so I was able to make myself a lovely game corner to entertain myself between killing zeds!
