Okay, so I recently created an infection map that actually favors zombies instead of humans. there are no camping spots on the map that i know of from my playtesting and there is absolutely no escaping the map. The only way to win as a human is to use teamwork. Here is where the map fails a little bit. I made the map have many places equally viable as a hold out. however, since all the places look good, there is no one place that humans go. therefore, everyone just kinda spreads out. It takes a minimum of 2 people to hold down any location but no one wants to work together. Should this map be released or should I do something different with the map.
I think after playing it a lot and losing, the humans will realize that they need to stick together. Because it doesn't sound like the maps fault, it sounds like the players fault. You should try testing it with dfferant groups of people.
