Hello All, I just have a quick question maybe someone can answer, and if it has been already answered if you can point me to the right thread? My buddy and I we started a multiplayer server and was wondering if its possible to change those settings mid game? Origionally we had zombie respawn set every week with a normal amount but its gotten a little easy now that we have established ourselves and was wondering if theres a way to up the count without losing map progress? Thanks a lot guys!
