I'm in the swamp and its dreary. Never been a fan of undead or never seeing any sun in there, I'm content with them just raiding my base. I can see the dreariness of the swamp finishing off some gamers who thought they had just made some progress by getting through the Black Forest.

I do the swamp in bits and pieces and just go hunt deer/boars and neck in the meadows which I find relaxing. Gives me a chance to have some sunny days. Lord knows it rains enough in this game.
