Hi, I got an idea, I found that twin falls have a bridge to repair for connect to other map. So i am thinking why don’t the Crate Entertainment connect the map all to 1 huge map for end game plus mode of course by completing some mission etc etc… .This gonna to be fun. Monster level scale to player level +1~+5 even more.
I hope developer could think about that. Thanks
Welcome to the forum. 
The bridge at Twin Falls can be repaired, but it has to be done from the other side.
