Personally, I love the mod. Unfortunately, I have only gotten to experience one new enemy from the added content -- The Baby Scorpion.
I think that a lot of people who are attempting to enjoy this mod are trying to access the desert area. And, similar to my experience, they have not found it. How do you get to the beach?
Side note, I think there should be a wiki set up by the mod creators for those of us that don't care about cheating, and inform us on how to get to the beach.
