Build 42, yeah i use some mod for the older version, I often play build 41 because all the mods I use haven't updated to 42 yet, Such as Brita Weapon, Brita Armor, Common sense, combat text, and several other supporting mods
I've bought Project zomboid from Steam and been playing it alone ever since, Hours alone, getting bitten, and creating new characters, over and over again until I started to get bored.
So maybe someone is interested in playing together? I don't have any friends to play with at all.
